At 13 weeks, your little baby is growing at a steady speed. If you could see through your abdomen, this is how your 13 week fetus would look like. A large head measuring half the size of the entire body, thin transparent skin with organs and veins visible, moving about in the amniotic fluid, flexing arms and legs. It’s a pretty sight to even visualize that this lovely creation is happening right inside you this very moment.

Bones and muscles are getting stronger day by day.

Fingerprints are beginning to form on those little fingers which will give your 13 week old baby an individual identity.

Salivary glands begin to function and the mouth makes sucking motions, to practice for feeding after birth. The jerky limb movements help your little one and he/she might be able to bring the thumb to the mouth and start sucking. The first complete movement of his life and this very action will help the baby to soothe itself as it initiates the sucking reflex.

The skin and hair follicles continue to grow.

The intestines are growing and moving to their permanent location that is the abdomen. All vital organs have formed and they are now beginning their functions – like the pancreas begins insulin production, the kidneys begin urine formation, etc. The urine formed is excreted into the amniotic fluid surrounding your 13 weeks fetus.

The placenta is also growing in size and is functioning in full force to sustain and nourish the baby.

Now that you are in your second trimester you will have a 13 weeks pregnant belly, your little bump begins to be visible. With nausea and vomiting on the decline, you are getting your energy back and beginning to feel more normal. The only bad news is that the fatigue and tiredness which has given you a temporary break will be back in the third trimester. Since each pregnancy is different from the other and unique in its own way; depending on your body type and to some extent your genetic tendencies, some ladies may continue to experience symptoms like nausea, vomiting and breast tenderness well into their fourth or fifth month. Such severe cases of vomiting are diagnosed as “Hyperemesis Gravidarum” and require appropriate treatment.

Your uterus is growing upwards and so it may push your belly button towards the outside.

There is a change in the amount of vaginal discharge in pregnancy. Hygiene habits play a very important role here. Remember to keep your private parts clean and dry at all times. If the discharge is too much, you may use a thin pad or panty liner. The two most important things to AVOID in pregnancy are use of tampons and douching – which is cleaning the vagina by pushing water inside. This will disturb the normal vaginal flora and can increase the risk of pre-term labor.

Your sex drive may begin to get back to normal around the second trimester but in case of any doubt, it is best to consult your caretaker especially if you have had a previous miscarriage or bleeding in the first trimester.

By this time, someone might have surely asked you this as to how many months pregnant are you, and your confused mind must have started converting 13 weeks in months. Well it is roughly 3 months.
