So during hooking up with a guy I “got my period” or so that’s what I thought even though so wasn’t supposed to get it for another 5 days. I usually have spotting right after sex anyway but this was like a lot of blood like I got my period. The next day it spotted and then went away and then the next weekend I had some blood again like I got my period (not during sex this time). Even though I’m on the pill my period does still tend to be irregular. Should I get this checked out or is this a normal occurance?
