HELP PLEASE!!

Ra

I had a positive ovulation test on Tuesday and have been spotting since then. It’s like pink/brown and some of it looks to be like it’s mixed with cervical fluid. My bf and I usually have sex nearly every day. We started having sex again on the 3rd but before that we weren’t having sex because he was out of state. Has this happened to anyone else? I’m so scared. Also my bf has a pretty big wiener to the point he hits my cervix sometimes and so cooch can hurt after sex. My next period isn’t due til about 8 days.
