Hello mam, age: 18 height: 5'2 weight: 41 9 days ago I had sex without protection and after 2 days I experienced breast pain then the next day slight back pain and after 3 days vaginal pain. The pain is in the area from where penis is inserted it also feels itchy and it pains while I go for washroom. My periods date last month was 5th. I also tested with the pregnancy kit which came negative I wanted your opinion for knowing: are these pregnancy symptoms? Is this because of some infection? Or maybe some other reason? What is the solution for this problem? I would be really glad it you can help me out on�this. Thank�you.
