What do you guys think? Could I be pregnant?

I had unprotected sex, but my partner did not cum in me. I know it was a stupid idea, but we didn’t get very far. This was on the 15th of August but I took plan b within 4 hours after. My ovulation was said to be a week prior to that on the 10th of August. I got a drop of blood on the 22 and then what I felt was my period on the 23rd-27th. Now my period for September is late and I’m kinda scared because I’ve been having pregnancy symptoms. I took tests and the last one was very faint with a positive but I don’t know if it was just a evap line because no one else was seeing it in photos. Help y’all. Now my right ovary hurts and my pelvis and lower back has been on fire. Thank you to whoever helps me out.
