birth control
"I absolutely loved OrthoTriCyclen! I was always irregular and had very bad mood swings, cramps, headaches, and nausea associated with PMS and my period. The first couple of months, I experienced occasional nausea and dizziness but that's to be expected when starting a new hormonal treatment. My periods shortened to four days instead of six or seven and I was able to pinpoint my periods each month while on the pill. I stopped taking it for a few years but I'm getting ready to get back on it this next week and I'm looking forward to it! After I stopped taking it, however, my periods became irregular again after a few months of discontinuing the pill."
