I am 16 year old and on tuesday i forgot

Patient: I am 16 year old and on tuesday i forgot to take my pill but i took it on wednesday, then on Thursday I forgot to take again and me and my boyfriend were going to have sex but we googled that the pill protects for one day so he ejaculated inside, then on friday (a day after) my vagina started bleeding but i didnt notice until we were having sex then we stopped because there was blood on him, i went to the toilet and checked and it was normal blood coming from me and not period blood, his helmet the next day had a big rash so he put soothing cream on it and now its fine but my vagina is still bleeding and for weeks ive been having very sore stomach aches and i dont know what this is.

Symptoms: Sore stomachs, constantly bleeding vagina
