Trying to avoid stretch marks ??

Carol
A lot of my friends who have gotten pregnant have stretch marks on their belly , thys and inner thy .. I'm not perfect I wasn't always skinny and I have my share but how do I prevent a lott of stretch marks during my pregnancy ? What do I use ? I seriously have a fear of being judge because I have them and I don't want to scare my future hubby away .. If I ever get married .
