What's happening to you: Beginning at your twenty-week visit, your provider may measure your abdomen to check your baby's growth; he or she can estimate the baby's size by measuring from the top of the pubic bone to the top of the uterus.

Having a hard time seeing the eye chart? That's because estrogen can cause physiological and vascular changes in your eyes, leading to vision changes and dry eyes. Normally, your tears come from the upper outside of your eye and travel across your eyeball to drain into your nose. When estrogen spikes and swelling changes occur, your eyeball bulges outward, and your tears flow straight down instead of keeping the entire eye lubricated. Often, these changes resolve after pregnancy. In the meantime, you may want to switch from your contacts to glasses; there's a possibility that contacts may stop fitting properly, drying out the eye and potentially leading to some corneal damage.
