"i know all of you are probably freaking out, crying, and suddenly looking into the future that the next 18 years might bring--- don&#039;t. i took the pill and didn&#039;t honestly need to, but my anxiety of course told me i needed to. april 1st i started my routine period which lasts about 5 days, i took the pill on the evening of april 12th. side effects: this was the kicker for me. i experienced slight headaches the first few days, but then april 16-17th i started bleeding which freaked me out. it was brown/bright red spotting, and lasted 3-4 days. i had cramps and my lower back killed me (still and it&#039;s the 21st). i know i&#039;m not pregnant, but i know my cycles will definitely be messed up. will never take again."
