Hi so I have been on birth control for the last 2 and a half years but I recently went off (no I am not trying to have a baby, just for other health reasons). My expected period was the 25th. I did not get this period. However, I did get a 48 hour light bleed on the 20th, but like I said it only lasted 48 hours. I know it sounds very similar to implantation bleeding. I took an EPT that Thursday the 25th after the short spotting and that was the day of my expected period and it did come out negative but I still haven't gotten my regular period. I have another test. Should I retest or do you think it's just going off the pill that's messing with it?
