I am 22 year old and in a healthy long distance relationship. I met my boyfriend after a long time and had protected sex for 5 times and unprotected once in 2 days, le 18th and 19th march. I had my last period on 10th feb. Although they are usually irregular, I was expecting them by 15th March. I have severe burning sensation in my vagina every time I pee. I have following three concerns: 1. Has the period been delayed further because of excessive sex? If so, what should I do to make them normal? Or you have any other theory and treatment? 2. Is it normal to have that burning sensation even days after the act? 3. I should not have any chances of pregnancy as he pulled out during the unprotected sex. Comment?
