Hello. I'm sorry you're having problems. The most common cause of vaginal bleeding after sex is cervical friction (that is, your partner's penis striking your cervix). However, there are a number of other conditions that can trigger spotting, such as a cervical polyp
, a uterine fibroid
or endometriosis. And, since you're having unprotected sex, another possibility is a sexually transmitted disease
Given the persistence of your bleeding and pelvic discomfort
, it would be wise to see a gynecologist to make sure there's nothing serious going on here.
I hope that helps!
