Stopped Birth Control after 15 years

Andrea
I have been on the pill since I was 16 years old. I'm going on 31, and married for 6 months/together for a total of 7 years.  My husband will be 37 in July.  I decided it's time to get off the pill.  Not because I am looking to get pregnant right away, but because I want it out of my body.  I've only been off of it for two days now and I have the worst headache and cramps.  I'm scared that my body is going to go into shock after all these years.   Anyone experience crazy symptoms when dropping the pill?
