"i had unprotected sex two days before my period ended and he came in me. i still took the pill a day later out of precaution even though i was on my period. it is two days after i took the pill and there is so much pain i cannot express. i restarted my period completely even though i was off my period for only a day. i&#039;m drained of energy and having severe cramps and muscle aches. i really hope this is a sign i am not pregnant."
