Hi.. Im 18, i dont know how to start, So Ive been having unprotected sex with my boyfriend for a year and a half, I have been using drugs for that time as well so i thought i could not get pregnant.. My period was about a week and a half ago, for some reason, i have no idea why, my boyfriend thought he could ejaculate inside of me, because im on my period. he thought i couldnt get pregnant on my period, And so he did finish inside.. My period was over the next day, 3 or 4 days have gone by and all of a sudden it looks like im on my period again? Normal blood , like a regular period...nothing like This has happened to me wether i was using drugs or not, my periods have always been perfect, no longer then 5 days.. Nothing irregular at all, ever. This is the first time ive ever had anyone finish in me.. Not on birth control , havent been for about 2 years... Is there any chance i could be pregnant? Maybe i did and it miscarried? Its probably too early to tell... Im just scared i never was irregular, until the first time my boyfriend ejaculated in me.. maybe its just a coincidence. idk... thank you so much!
