So I’m on a bc pill, I was taking it regularly then got a bit off track with it... was also having sex at the time unprotected... my period didn’t come on time so I strongly thought I could be pregnant because I hadn’t been keeping up with my bc and was having sex. Today I got my period (three weeks late) and just now I went to the bathroom to change my pad and found this. What the hell is it???? Should I be concerned???? I’m so confused and nervous and idk what’s happening. Never experienced this before.
