I also had excruciating periods - doubled up with cramps, vomiting, very heavy flow for several days. I went to my family doctor when I was 17 and he recommended I start the pill. I was on for 2 months then all of a sudden woke up one morning and couldn't breathe. Being the stubborn person I am, I got up, got ready and caught the bus to go to university (about 80 minute trip) Got to the station, got off the train and started walking to school. Went about 1/2 a block and decided it just wasn't happening and I turned around to go back. I called my mum from the train station, she picked me up and took me to ER. Turned out I had developed blood clots in the deep veins in my legs which then detached and found their way through my bloodstream to my lungs. The doctor figured that if I hadn't gone straight to ER after arriving back in town, I could very probably have died. Needless to say, I came off the pill and haven't looked back. I'm not trying to dissuade you from taking the pill - after all millions of women use it with no problems at all. Just be aware of the risks. There are reported incidence of between 15 and 30 blood clots per 100,000 women on the pill. Talk to your doctor, get ALL the information before you make your choice.
