So I had unprotected sex with my baby dad a few times. After the first time, I bought plan b just in case. The second time, I didn’t get plan b and the third time, I got plan b from my doctor because he said he came inside me a little that time (he CLAIMED he didn’t the other times) so, the day after the third time we had sex, I started bleeding...and my period was due around this time so I thought it was that but it was lighter than usual...I stopped bleeding after two days (my period has NEVER lasted two day. It’s always almost a whole week of bleeding HEAVY)...two days later, the blood was back when I woke up but later in the day, there was no blood. So I got nervous and thought this was spotting so I bought a two pack early prediction pregnancy test. They both were negative...so I started taking birth control again. But today I feel REALLY bloated and I started reading pregnancy symptoms and it really sounds like I was experiencing implantation bleeding....should I stop taking my bc? (I’ve only taken it for two days) and should I buy another test? Do you guys think that I could be pregnant?
