So I just stopped taking them and the bleeding literally stopped in 2 days ( wow thanks!!) That was June 26 but me and my man been having sex unprotected( stupid yes but I’m not the only one!) on July 1 he nutted in me.... it’s been a week and I had some light pink discharge for one day and now I feel like crap! Could it be the fact I recently got off or I’m just down right pregnant. Peep this! Me and the guy broke up so yeah please help
