Hi..i and my partner were indulged in protected sex were in she had unexpected vaginal bleeding after orgasms. Her periods have been irregular since long and she hasnt got one since two months..i am confused that is it a sign of her periods starting. To be noted that we were involved in an unprotected one 10 days ago where she had her frst birth control pill to avoid pregnancy and checked negative in a 7 day gap..was bleeding a sign for pregnancy? I am confused can you help me out what the bleeding might be off?
