I am 22 years old lady. I had 7 times sex with my fiance during my 3rd day of menstrual cycle. Out of which 2 are unprotected and 5 are protected. This is our first time that we had sex and lost our virginity. And we both are not having any disease. A week after this, I found irritation, itching near vagina specially around labia region and burning while urination. Thereafter drinking a lots of water that burning sensation at genital region during urination had gone. 10 days after sex I found my left labia minoris is stretched out, it has slightly increased in size as compared to right labia minoris and both labia majora are partially swollen at few patches but I feel sometimes itching though it has reduced as compared to earlier but it still sustains. Now I'm worried about it very much. Kindly tell me what are these symptoms mean to be?
