10 weeks... stretch marks?!?

I'm 10 weeks today and when I looked at my stomach this morning it has what looks to be stretch marks already :( I don't even have a bump yet so idk how it's possible... could it just be my veins? I'm kind of chubby so my stomach looks like I have a bump but it's not from the baby I'm sure. Anyone else have this? I've never been pregnant before and these weren't here before my bfp either.
