So I'm kind of scared, my boyfriend and I had unprotected sex.. But he didn't cum in me at all, I am now according to glow, 8-9 days late for my period, I've been stressing about it a lot, could I just be freaking myself out and delaying it even more? Plus, I only have one period logged into glow, is it really that accurate? I'm so scared. I'm only 19.
