Spotting

I had very light brown spotting four days after sex, went to the OB, and there was just a very irritated blood vessel on my cervix—I haven’t had any spotting since, everything seems totally fine, and it seems most likely that it was just from the sex even though it had been a few days (as my OB said, “the vagina is expansive” lol, and blood can end up just sitting in there for a while). But if you’re concerned about it then I’d definitely give your OB a call!
