What should i do about vaginal bleeding i had sex on saturday morning and after that i have been experiencing vaginal bleeding. this is the first time this has ever happened to me

If : If you are not on your period, the most common source of vaginal bleeding after sex is from the cervix - the part of the uterus that hangs into your vagina. Your bleeding after sex is most likely just cervical irritation from the friction of sex. As long as you are premenopausal, the bleeding is infrequent (which is true since it's the first time it happened), and you have normal, regular pap smears, then you don't have to see your doctor for it. If you are postmenopausal, have bleeding that is heavy or every time you have sex, or if you have had abnormal paps smears in the past, you should see your doctor to rule out more serious causes such as cervical cancer. Good luck!
