Week 3 of pregnancy

| | ,

Congratulations! If you have made it past the first two weeks of pregnancy, you have mostly conceived a baby at the beginning of pregnancy week 3 of pregnancy or the end of the second week. During week 3, a little new life begins to take form.

Whether planned or not, pregnancy can have a huge toll on a woman’s life for the next nine months and this is just the start. The sperm has most likely found the egg and fused with it, resulting in a single-celled body called a zygote, which starts to actively divide in the next few weeks. 

What does week 3 of pregnancy look like?

At this point, it is hard to find out about pregnancy as the baby is too small to add a profile to your abdomen. It is an early stage of pregnancy, so the changes will be quite subtle. You may not find any physical symptoms indicating your pregnancy. It is a period between ovulation and fertilization of the egg and sperm.

If you are trying for pregnancy, you must already be well versed with the day your next menstruation is supposed to start. Thanks to all the online apps, you don’t need to break your head with all the calculations. Now keep a note of that day and if you miss it, it might be possible that we hit a home run! Wait for another week and if you still didn’t get them, you can proceed towards getting a pregnancy test done.

There are numerous urine pregnancy tests available at the local medical stores. These are super convenient but less sensitive. Meaning – if you get it positive, hurray. But you may get it negative even if you are actually pregnant. So, we highly recommend visiting your local OBGYN and getting a blood test done.

Week 3 of pregnancy

What are the symptoms?

It is noted that during the early period of pregnancy, you might not see any major symptoms as the pregnancy hormones are very less in the body at this point. Some of the symptoms you are most likely to observe during this week or by the end are-

1. Anxiety

Experiencing emotional changes is the one of the first signs of pregnancy that are subtle, caused by change in hormones and body. You may feel nervous and anxious at times without any reason and may get a bit more sensitive.

 The intensity of the emotions varies throughout time and it is quite normal. Not everyone gets this symptom but is a consequence of an increase in pregnancy hormones. 

2. Feeling tired unexpectedly

You might feel tired more often than usual. It is easier to observe these symptoms among women who usually don’t get tired quite often. Although feeling tired can be due to many reasons and it is hard to locate it as a pregnancy symptom. 

Morning sickness should be called as all-day sickness since it doesn’t discriminate by time of day. You might feel tired more often which can be a sign of the good news.

3. Spotting

When the embryo reaches the uterus, when it burrows itself in the uterine lining, it sometimes causes a small amount of bleeding or spotting which is normal.

Some women don’t get this symptom and may also vary from pregnancy to pregnancy. If there is no spotting, it doesn’t mean you are not pregnant. Implantation is most likely to take up mostly in week 4 but some women notice it in week 3.

4. Soreness in the breasts 

Due to rise in pregnancy hormones, the breasts start to get sore. The nipples get sensitive and darken. You might feel occasional uneasiness and pain in your breasts.

5. Positive result of pregnancy test

By the end of week 3, you are most likely to test positive if you have conceived. Here’s the thing: the number of pregnancy hormones might not be enough to detect in the early days of the week or sometimes, the test results might be positive in the next week. The hormones double up every 48 hours. If you have found the test results to be negative, wait for a few more days or a week for another pregnancy test.

Fetal development at week 3

No physical signs can be noticed during this period. Don’t expect any changes in your belly at this time. It has just started! Most of the women physically show signs of pregnancy at week 12 or so. By the time you notice physical changes, you have already come a long way in this journey.

Once the sperm fuses with the egg, the structure of the egg changes so that no other sperms can interfere with the fusion. The zygote is very tiny at this stage, similar to the head of the pin.

This single-celled zygote divides itself into multiple cells after the next few days and moves from the fallopian tube to the uterus, where the fertilized egg settles itself upon the thick cervix lining. From that time, your menstrual cycle stops.

Self-care tips 

Work on your diet

Make sure you have enough prenatal supplements along with a healthy diet to ensure that the egg is not affected in any way due to bad diet habits and consumption of alcohol or drugs. Stop consuming drugs or tobacco in any form to increase the chances of pregnancy and reduce pregnancy complications.

Vitamins aren’t substitutes for a good diet but they complement and fill in the gaps of extra nutrition that the body requires. Have plenty of water, always.

Do required amount of exercise

Doing exercise is a great way to combat stress and ensure that the body is physically strong enough to handle pregnancy complications. Experts recommended 150 minutes of physical exercise per week for normal healthy individuals.

Don’t get on a new exercise regime now, you can continue your previous exercise schedule if you have one. Or else start with some low impact exercise and stretches and try to do them regularly to see some results.

Create a positive outlook

It is important to have a healthy mindset, just like being physically healthy. This week marks a change in mood and emotions, which can take a toll on the woman’s mental health. Seek advice and share your experiences. Join discussion groups or communities for support. Practice mindful exercises and indulge in some hobbies or activities that cheers you up!
