There's a lot of conflicting information on the internet about this. We had dry sex in our underwear and he said only pre-ejaculate came out, but I could feel something wet. Though, I'm not sure if the wetness I felt was from him or from me. This happened on the last day of my period with my usual cycle of 31-35 days. Is it possible that I'm pregnant?

I'm having sharp ovarian pain on my right side that's starting to go down my leg. I'm supposed to start my period around the 12th. My period can range from every 4-5 weeks normally. I'm confused if it's just ovulation pain or if it could be if I was pregnant
