Tiay - you need a new family. I will let you join mine. Don't worry about the stretch marks. They happen when skin stretches due to rapid growth, and they are largely genetic. They will fade after you've had them a while. For the record - there is nothing that will help with pregnancy stretch marks. Look at your mom's tummy. If she has stretch marks, you are doomed, no matter what you stick on your belly.
Relax... I'll need some information first. Just the basic facts - can you show me where it hurts?
