I am only 5w6d and already starting to get stretch marks....sort of. I have small stretch marks from my first pregnancy that I started getting at 8 weeks. These are starting to get longer and get red and itchy. Along with the old ones getting bigger I have a few dark red new ones. I know  it's not impossible to get them this early but it is highly improbable considering the baby is only the size of a chocolate chip. Could it mean twins? It's making me really nervous! Does anyone have any advice or have you experienced stretch marks this early?
