Question

Hi soo i have a question for you my ladies... okay so in the past month i thought i might have been pregnant but then my period was just late by a week and so my period lasted the normal amount of days and everything and ive had sex with the same person 2 or 3 times since my period ended well tonight i had unplanned sex with someone else and for some reason afterwards i was bleeding. Could anyone tell me why i dont bleed after sex with the same person multiple times but i do bleed after having sex with a different person once? I could really use the help thank you ladies.
