HELP PLEASE

hi i was wondering if anyone could help me. i had sex on the 4th of November and took the morning after pill the next day however a condom was used too but after he came he put another condom on the wrong way then the right way and we had sex again.Then on the 6th of November I started taking birth control and took a pregnancy test around the 27th of November and it was negative then i bled for around 2 weeks lightly but enough for a sanitary product. I then stopped taking birth control at the start of December and have since not had a period and i am experiencing heartburn and some nausea but have been drinking heavily over 4 days.I recently took another pregnancy test and the results did not come up after 5 minutes but I checked a few hours later and there was a faint negative line. I have also been experience bloating but I’m not sure if that’s me just overthinking it as I would be 2 months pregnant by now if I was. Is my period late due to the amount of hormones i was taking in a month or could it be possible I’m pregnant?
