so i finished my period today. there was light spotting throughout the morning, but it was a darker brown color. in the afternoon i decided to take the risk and have unprotected sex w my bf, and he came in me. i went to the bathroom after and i was bleeding a lot, like it was my period continued. hes came in me before and i bled, but not this much. there wasn’t clotting or anything but it was clearly blood, and a different color then when i finished my period earlier in the day. any idea if this is related to my birth control? or is it just my period ending? im on the pill btw
