Bleeding after sex

The other night my parter and i had sex that was a little more aggressive then usual, i enjoyed it and so did he but it started to hurt a little after he finished and we decided to stop. He’s quite large down stairs so it’s not unusual for it to hurt a little after but it’s been about 3 days and i still feel a bit of discomfort and started bleeding about 2 days ago, it’s not much and has gotten lighter throughout the days just wanting to see if other people with larger partners have experienced this or if i should potentially be worried about implantation bleeding or anything else, we usually wear a condom and I’m on birth control but we didn’t have any condoms left so we decided because I’m on birth control we didn’t really mind not using a condom (we are both clean just use it as an extra bit of protection 80% of the time)
