Hiya I need some help or somethin I have an implant n I had my period about 1 or 2 week ago but last week my bf came in me by accident and he couldn't help it because he split his bango a little, we sometimes use condoms but I feel like every time he cums in me I seem to start spotting (little signs of period) and I don't understand why though..... help please xx
