During pregnancy week 7, your baby will grow tremendously, up to 13 mm in length!

Facial features are becoming more prominent in your baby. Upon close investigation, you may be able to discern a mouth and even a tongue (you actually can't see the tongue, but it is forming inside your baby!). Your baby's eyes will also start to become more fully formed, and the eyes now have a retina and lens attached.

The major muscle systems in your baby's body are continuing to develop, and your baby's liver is working diligently to produce red blood cells. Movements will be uncoordinated at this point during pregnancy, but rest assured your little one is squirming about his or her new home.

If you were to look directly at your baby, you would still be able to see slight webbing in the fingers and toes.

Your baby's liver is working diligently to start producing red blood cells.

Now that you’ve reached pregnancy 7 weeks, you may have noticed that you’re producing more saliva than usual. If you’re suffering from morning sickness or heartburn, you may find that this strange pregnancy symptom is more of an annoyance. This is a condition called ptyalism, and it’s common in the first trimester.
Other pregnancy symptoms you may experience at 7 weeks pregnant include fatigue, frequent urination, and headaches. These are normal symptoms to expect during pregnancy week 7, and they will decrease in severity once you hit the second trimester.

You can blame hormonal changes for your symptoms at pregnancy week 7. In the first trimester, you have a surge of hormones in your body. Hormones tend to level out in the middle trimester – which is often referred to as the “honeymoon” of pregnancy.

Your weight gain at 7 weeks pregnant isn’t much – roughly only one or two pounds. You don’t look pregnant yet, but some women may start to notice a little pooch in their lower abdomen.
