My best mate didnt get them til 38 weeks. She cried when they came. I didnt get them til 27 either. I think its genes, and how far ur skin has stretched before. Get some moisture on them !
I've never worried about my stretch marks. I wear a bikini I flaunt in crop tops. I carried 2 babies with my body. I've used oils creams and such to stop itching but not to stop them. In the end girls we will have stretchy skin saggy boobs and happy babies. My husband still attacks me at 36 weeks pregnant in the kitchen. He cuddles me loves me thanks me for our children. Maybe if people worried less what others think and body image we could all be happy with our self's.
