You may know that there aren’t any real changes during the first week of pregnancy, but it is pregnancy week 2 when things might get a little more interesting.

The changes you experience during 2nd week of pregnancy

The second week of pregnancy is considered the week following after the end of your period. The lining of the uterus thickens and it prepares for nourishing the baby.

The interesting thing about this period is that in the majority of the cases this is when ovulation occurs, so it is very likely that you aren’t pregnant yet. Nonetheless if you would like to become pregnant, this is the best time to take action.

Also consider that during pregnancy week 2 you have only little time to fertilize the egg, because it is fertile for only 12-24 hours.

Your hormones also change, and the body releases more estrogen. This way the body prepares for the pregnancy and also you may experience higher levels of energy and creativity.

Fertilization in the 2nd week of pregnancy

Fertilization occurs in the moment when the egg and the sperm meet in the fallopian tube, becoming one entity, known as the zygote. According to this, in case there are more than one egg released, you will have twins. The zygote will have 42 chromosomes, half of them from you and the other half from your partner.

These will determine different characteristics of the little one, including eye color, height, hair color, facial characteristics, personality and also intelligence.

After fertilization, during pregnancy week 2 the zygote gets to the uterus through the fallopian tube. During this it also starts dividing into more cells. The inner cells will be the baby, and the outer cells will become the membranes that protect it.

Although at this moment the baby is smaller than a rice grain, the cells divide very fast and there are many organs to develop, such as the digestive tract and the immune system.

A lot of women get disappointed if they don’t get pregnant for the first try. You should be aware of the fact that the chances for you to get pregnant is of 25%, and the chances decrease as you get older.


Pregnancy week 2 is the perfect time to find a healthcare provider that is going to take care of you during your pregnancy. You have a lot of options when it comes to this, including an obstetrician or obstetrician-gynecologist.
