Hey, I'm 8 weeks pregnant, and I already have some killer stretch marks on my stomach 
I was pregnant last year up to 16 weeks and just got one big stretch mark running down from left of my belly button, and that one never faded, but now it's got friends! 
They feel like my stomach has split, and they're very red and tender.
I may just be getting fat, but I've been a little overweight for a few years now (size 16, 13stone) and never got stretch marks til post-BFP.
Has anyone else had them this early?!
