Following are a few symptoms that you are going to go through during your third week of pregnancy.

Implantation bleeding

Your baby is going to travel its way through your fallopian tube to your uterus where it is going to attach itself to your womb. During this process, you may feel some bleeding or pinkish discharge. That is known as implantation bleeding.

There is nothing to worry about in that regard. If you bleed, rest assure that your baby has made its way up to your womb and now the further process shall begin.


Nausea is something that is not going to leave you along for a few weeks now. Early morning sickness is one of the most common symptoms faced by pregnant women during the early weeks of pregnancy but in case it gets out of hands or is too much to bare, you must talk to your gynecologist.

Breast changes

Your breast is going to start feeling little to a few changes in the third week. There is nothing very evident, but you will feel your breast to be a lot tender than before. By the third week of pregnancy, your blood has begun to increase.

You may feel soreness and discomfort in your breasts along with prickling and tingling sensation. You will notice your veins to be more prominent and your older bras may not fit anymore.

Heightened sense of smell

Another symptom that you’re going to feel is the heightened sense of smell. Your nostril will smell anything and everything in even a block’s radius away. This is another reason why your nausea will be at its peak because you will literally smell anything and everything in your surroundings.

Positive home pregnancy test

As mentioned before, by the third week of pregnancy, you must have gone through to the doctor by now because it definitely has been two weeks since you didn’t get your period. But in case you haven’t, doing a home pregnancy test will also now result positive for sure.

Lower abdominal pressure

It isn’t like cramps and is nothing that you cannot bear. Just rest as much as you can.

About your belly

At this point, your baby-to-be is too small to add any profile to your belly — enjoy it while it lasts!

3 weeks pregnant belly size isn’t something that is going to be noticed by anyone let alone you. Your body is hardly changing physically that can be evident. You belly is still the same and may have only increased an inch. Not more than that.

The belly is usually more prominent by the end of 5th month so there is time for you to enjoy your old clothes. But, some women, however, lose weight during the early weeks of pregnancy. That is mainly because of the hormones and the changing diet.

In case you want to avoid weakness and be on your strength, adopt rich protein diets and take as much fiber as you can. Eat fruits, exercise and take rest. Stay active but be moderate. Do not overwork yourself.

These first few weeks are very crucial, and you do not want to lose your baby just because you weren’t paying proper attention to your routine.
