I’m 28+6 and I’ve noticed for the past few weeks some very light red lines coming from my nipple area outward and it started on my left breast and now I see it’s happening on my right. So I’m going to guess it’s stretch marks? Funnily enough I don’t have any marks on my belly (so far) but my breasts- that have barely grown maybe a cup size and I started off with C cups- have marks lol. Anyone else?? It’s so random and I’m not bothered by them at all, it’s just arbitrary to me lol
