ok so i went to a party last night and i happened to take quite a large amount of amphetamine the whole night. i’m on combined pills and i get my bleed on the 3rd day of my break, which is today. i had some mild abdominal cramping this morning so i obviously thought my period is here/should be here soon til later in the day. all i got was some egg white consistency mucus with some blood particles inside. after a few hours i got a very slight pinkish-brown spotting, but not as if my period was just starting. now everything suddenly stopped but i still didn’t get my period. i did have unprotected sex in the past month and i have missed one pill, which i took the morning after as soon as i remembered, so i took a double dose that day. could the amphetamine have stopped my period? could i be pregnant and that was just implantation bleeding? i’m really worried.
