Your doctor also will keep track of your weight gain. Over the course of your pregnancy, you should gain between 15 and 30 pounds, depending on your weight before you became pregnant. Overweight women should try to limit weight gain to 15 pounds. For women of normal weight, an increase of 20 to 30 pounds is often recommended. If you take insulin, expect your insulin requirements to rise gradually to about week 20 and then accelerate dramatically.
Hormones made by the placenta to help the baby grow block the effect of the mother's insulin.
As a result your insulin needs increase significantly. At this stage of your pregnancy it's also important to see an eye specialist. Damage to small blood vessels in your eyes can progress during pregnancy because of additional hormones manufactured by the placenta. You may receive another ultrasound exam to assess the size and health of your baby. You also should have your eyes examined again to check for eye damage.
