I was curious becuz i'm not too sure on this but during what points in your pregnancy , do you start to show and when can you find out the sex of the baby?? Also I am soo bummed. I know that stretch marks are hereditary but I couldn't help but ask even though I believe this will happen to me. Well, I have 2 older sisters and with all three of my moms pregnancy's she got real bad stretch marks and gained alot of weight which she lost soon after she had us and my oldest sister has 2 boys and the situation was the same for her. Her freakin stomach looks like freddy kruger got ahold of her lol. Anyway she is beautiful no matter what and I love her to pieces . I put on cocoa butter everyday and i'm only six weeks lol. Please reply all comments. ~erica.
