Can't wait to get off birth control

Not sure if i've said this before but seriously I can't wait... it's not even my strong internal clock that is going TICK TICK TICK deep inside my body, I just simply HATE birth control pills. I hate the chemical hormones that I am putting into my body on a daily basis. I hate how it took my body well over a year just to regulate to the damm pills and now it seems that after only a few months of nice monthly periods I have somehow screwed up my system once again where I am getting horrible cramps for DAYS before and during each period. Like last night, the cramps started just prior to karate class... my whole body ached in pain, I took a Tylox when we got home and went to bed, within 30 mins of rising the cramps started up again and I felt like shit for the good portion of today, and let me tell you, still no period in sight! I thought I saw something HOURS ago but now nothing.. so then I wonder, am I pregnant? And then I freak and then I tell myself, no of course your not it's just your stupid body who likes to fuck with you and not be a normal human body!
