Bleeding after Orgasm

Amanda

So I was home alone, and did a little masterbation. My husband has a hardened vessel in his penis so I didn't bother him for sex, then I started spotting pink! It's slowing down already, 5 weeks along. I've read it's normal because there's more blood getting ready for baby, but has anyone had this happen before?

I feel so dumb! Sorry for the tmi
