Hello, I’m a female About 4 days ago, I had anal

Patient: Hello,I’m a female. About 4 days ago, I had anal intercourse with my boyfriend. It was only one thrust because it hurt but it went pretty deep. The day after I noticed pain, tingling, and sensitivity around the hole and it still continues. It has not affected my bowel movements and I have not noticed blood. Could I just be sore? I’ve never had a penis go in my anus before so it was very unexpected. I looked up pain after anal and it mentioned a possible STD. I was diagnosed with chlamydia back in December but I was treated. Could it be back? I’m going to try a warm bath tomorrow and how long do you think I should wait to go to the doctor?Thank you!
