so confused help pls ladies

I had blood  in my cervical mucus for a few days after my ovulation window was over. I would wipe and there was pink/brown blood Lately my stomachs been cramping and it feels bloated / heavy. Last night my husband I got intimate and that was the most painful sex I've ever had. I felt like he was hitting something  in there like my cervix or something. It's too early for me to test. My period isnt till the next 6 days. I wanted to go see a doctor today but I don't want to be wasting their time. I am so confused ugh . Afraid it'll end up just being an infection. But honestly my Urine is fine and has no odor nothing. I've had infections before but with that I had back pains , sharp stomach pains and headaches. This time it's only my stomach that cramps up like I am on my period or something. Sometimes I feel like my period started but I'll check and there is nothing. Is there a possibility it could be a start of something ?? Or should I just go to a doctor to test for an infection yet again 😩
