Pregnancy Symptoms Week 1: Early Signs

Eventually, some women have no early pregnancy symptoms at week 1, while others may experience symptoms such as fatigue, breast tenderness, and mild cramping.

Usually, medical experts measure pregnancy week 1 from the first day of a woman’s last menstrual period. Although a woman is not actually pregnant at this point, counting week 1 from the last menstrual period help determine a woman’s estimated pregnancy due date.

A missed menstrual cycle is often the primary symptom of early pregnancy.

Can you feel pregnancy symptoms 1 week after conception? 

A pregnancy test is the best way for a woman to determine whether they are pregnant or not.

Conception occurs when the ovary releases an egg (ovulation), and a sperm fertilizes it. This can happen about 14 days after the menstrual cycle starts.

When do the symptoms start?

Though it may sound odd, your first week of pregnancy symptoms is based on the date of your last menstrual cycle. Your last menstrual cycle is considered week 1 of pregnancy, even if you weren’t actually pregnant yet.

The expected delivery date is calculated from the first day of your last period. For that reason, the early few weeks where you may not have symptoms also count toward your 40-week pregnancy.

Pregnancy symptoms in week 1 

Pregnancy symptoms in week 1 are different for each woman and each pregnancy. According to the Office on Women’s Health, the most common first sign of pregnancy is a missed menstrual cycle(period).

List of week 1 early pregnancy symptoms include:

  • nausea with or without vomiting
  • breast changes including swelling, tenderness, or tingling feeling, or noticeable blue veins
  • frequent urination
  • headache
  • raised basal body temperature
  • bloating in the belly or gas
  • mild pelvic cramping or discomfort without bleeding
  • tiredness or fatigue
  • irritability or mood swings
  • food cravings or aversions
  • a heightened sense of smell
  • metallic taste in the mouth

But not all of these symptoms are unique to pregnancy. Also, remember that early pregnancy does not always cause noticeable symptoms.

The best way for a woman to find out if they are pregnant is to take a pregnancy test.

 

Pregnancy Symptoms: 15 Early Signs

1. Cramping and spotting

From 1 to week 4, everything is still happening on a cellular level. The fertilized egg develops a blastocyst (a fluid-filled group of cells) that will develop into the baby’s organs and body parts.

And about 10 to 14 days (week 4) after the conception, the blastocyst will implant in the endometrium, lining the uterus. This can cause implantation bleeding, which may be mistaken for a light period.

Some signs of implantation bleeding:

  • Colour: The colour of each episode possibly pink, red, or brown.
  • Bleeding: Bleeding is usually compared to your regular menstrual cycle. It is (spotting) defined by blood present only when wiping.
  • Pain: It may be mild, moderate, or severe. According to a study of 4,539 women trusted Source, 28 per cent of women associated their spotting and light bleeding with pain.
  • Episodes: Implantation bleeding is likely to last less than three days and doesn’t require any treatment.

More importantly, Avoid smoking, drinking alcohol, or using illicit drugs, which are associated with heavy bleeding.

2. The missed period

Once implantation is complete, the body will begin producing human chorionic gonadotropin (hCG). During pregnancy, this hormone helps the body to maintain pregnancy. Also, the ovaries stop releasing mature eggs each month.

Most likely you will miss your next period four weeks after conception. If you have an irregular cycle, you’ll want to take a pregnancy test to confirm it.

Most home tests can detect hCG as soon as eight days after a missed period. A pregnancy test will be able to detect hCG levels in your urine and show if you are pregnant or not.

Tips

  • Take a pregnancy test to know you’re pregnant or not.
  • If it’s positive, consult with your doctor or midwife to schedule your first prenatal appointment.
  • If you’re on any medications, ask your healthcare provider whether they pose any risk to your growing baby.

3. Raised body temperature

A higher basal body temperature possibly a sign of pregnancy. During pregnancy, your body’s core temperature may also increase during exercise or in hot weather. During this time, you’ll need to make sure to drink enough water and exercise cautiously.

4. Fatigue during early pregnancy

It can develop at any time during pregnancy. It is a common symptom of early pregnancy. Your progesterone levels will also soar, which can make you feel sleepy.

Tips

  • The first early weeks of pregnancy can make you feel exhausted. Try to get proper sleep.
  • Keeping your bedroom cool can also help you. Your body temperature is possibly higher during the early stages of pregnancy.

5. Increased in heart rate 

Around weeks 8 to 10, the heart may begin pumping faster and harder. Palpitations and arrhythmias are common in pregnancy. It is due to hormones.

Increased blood flow due to the fetus happens later in pregnancy. However, management starts before your conception, but your healthcare provider can help supervise low dosages of drugs if you have an underlying heart problem.

6. Early changes to breasts: Tingling, aching, growing

It can occur between weeks 4 and 6. You’re likely to develop tender and swollen breasts due to hormone changes. It is likely to go away after a few weeks when your body has adjusted to these hormones.

Nipple and breast changes can also occur about week 11. These hormones continue to cause your breasts to grow. The areola — the area around the nipple — may become a darker colour and grow larger.

If you’ve had bouts with acne before your pregnancy, you may also experience breakouts again.

Tips

  • Relieve breast tenderness by using a comfortable, supportive maternity bra. The cotton, underwire-free bra is often the most comfortable during pregnancy.
  • Choose one with varying clasps that give you more room to “grow” in the coming months.
  • Also, purchase breast pads that fit into your bra to reduce friction on your nipples and nipple pain.

7. Changes in mood 

Your estrogen and progesterone levels will be high during pregnancy time. During pregnancy, this increase can affect your mood and make you more emotional or reactive than regular. Mood swings are normal during pregnancy, and they may cause feelings of depression, irritability, anxiety, and euphoria.

8. Frequent urination and incontinence

During pregnancy, a women body increases the amount of blood it pumps. It causes the kidney to process more fluid than usual, which leads to more fluid in your bladder.

Hormones also play a role in bladder health. You may find yourself running to the bathroom more frequently or accidentally leaking during pregnancy.

Tips

  • Drink 300 ml (a little more than a cup) of extra fluids each day.
  • Also, plan out your bathroom trips ahead of time to avoid incontinence.

9.  Bloating and constipation 

Bloating may occur during early pregnancy. It may be due to hormonal changes, which can also slow your digestive system down. You may also feel constipated and blocked as a result.

Constipation can also increase feelings of abdominal bloating.

10. Morning sickness, nausea, and vomiting 

Nausea and morning sickness usually appears around weeks 4 to 6. Morning sickness can occur any time during the day or night. It’s unclear exactly what causes nausea and morning sickness, but hormones may play an important role.

During the first trimester of pregnancy, most women experience mild to severe morning sickness. Morning sickness may become more intense toward the end of the first trimester but often becomes less severe as you enter the second trimester.

Tips

  • Keep a package of saltine crackers by your bed and eat a few before you get up in the morning that helps you settle morning sickness.
  • Stay hydrated by drinking plenty of fluids.
  • Consult with your doctor if you cannot keep fluids or food down.

11. High blood pressure and dizziness

In most cases, high or normal blood pressure will drop during the early stages of pregnancy. It may also cause feelings of dizziness since your blood vessels are dilated.

High blood pressure as a result of pregnancy is hard to determine. Almost all cases of hypertension during the first 20 weeks indicate underlying problems. It may appear during early pregnancy, but it may also be present beforehand.

Your healthcare provider will take your blood pressure during your first visit to help establish a baseline for a regular blood pressure reading.

Tips

  • Consider switching to pregnancy-friendly exercises. 
  • Learn how to monitor your blood pressure regularly.
  • Consult your doctor about personal dietary guidelines to help reduce blood pressure.
  • Drink enough fluids and snacks regularly to help to prevent dizziness.
  • Standing up slowly when getting up from a chair may also help.

12. Smell sensitivity and food aversions 

It is a symptom of early pregnancy that is mostly self-reported. There’s little scientific research about smell sensitivity during the first trimester. But it may be as smell sensitivity may trigger nausea and vomiting. It may also develop a strong distaste for certain foods.

13. Weight gain during early pregnancy

Weight gain becomes more common towards the end of your first trimester of pregnancy. You may find yourself gaining about 1 to 4 pounds weight in the first few months. The calorie requirements for early pregnancy won’t change much from your regular diet, but they will increase as pregnancy progresses.

In the later stages, weight often spreads out between the:

  • breasts (about 1 to 3 pounds)
  • uterus (about 2 pounds)
  • placenta (1 1/2 pounds)
  • amniotic fluid (about 2 pounds)
  • increased blood and fluid volume (about 5 to 7 pounds)
  • fat (6 to 8 pounds)

14. Heartburn during early pregnancy

Hormones can cause the valve in the middle of your stomach and oesophagus to relax. It allows stomach acid to leak, causing heartburn.

Tips

  • Prevent pregnancy-related heartburn by eating many small meals a day instead of larger ones.
  • Try to stay sitting upright for at least an hour to allow your food more time to digest properly.
  • Consult with your doctor about what may be safe for you and your baby, if you need antacids.

15. Pregnancy glow and acne 

Many women may begin saying you have the “pregnancy glow.” The combination of increased blood volume and higher hormone levels pushes more blood through your vessels. It causes your body’s oil glands to work overtime.

This increased activity of your body’s oil glands causes your skin a flushed, glossy appearance. On the other hand, may also appear acne.
