I had sex and ended up taking plan b on april 12. About a week or a week and a half i ended up getting an early period (seemed way too early to me cause mine had already passed during the beginning of april and ended not to long before i had sex. ) its been ever since my early period ended (took about 5-7 days. Typical for me) i haven't had once since. I'm starting to worry and yeah i have missed a period before but i wasn't having sex at the time and it was way too long ago. My periods are irregular and always move around the month. But I'm starting to worry. I've had to take plan b before but my periods always remained the same. This time i still have gotten my cramps ans other pains as usual and maybe I'm getting a bit desperate. I'm scared. Is this normal? What steps should I take? Idk if it helps any but I'm 24 and living in tx.
