During this part of your pregnancy it will be clear from your physical appearance that you are carrying a baby! You are growing, and with this growth may come stretch marks. Almost all women who go through pregnancy will get stretch marks on their abdomen. Some women also get stretch marks on their breasts, hips, and buttocks. The skin is being stretched by the growth of the baby and enlargement of your breasts in preparation for breastfeeding. There are lots of lotions on the market for treating stretch marks, but, unfortunately they don't work. There's just no way to prevent stretch marks. During your pregnancy they may appear red, brown, or even purple. Once you deliver they will fade and turn a more silvery shade and won't be as noticeable.
