few days ago, I had sex with my husband, we were intimate for a few seconds, then I had vaginal bleeding. At first there was a little fresh blood, then it was dark red blood with a little fluid. I did not have any pain in my abdomen or vulva, but the bleeding continued for at least 2 days. Although it was not much, I was very worried. Doctor, what is the cause of bleeding during sex? Because of the Covid epidemic, I have not been able to go to the doctor. I hope the doctors can advise.
