I have had a history of heavy menstral flow, and cramping. I started getting my period twice a month ( Really!! Once was bad enough ) My doctor suggested seasonale and I jumped at the chance to have only 4 periods a year. Within 4 days of taking the pills, I started spotting , which turned into a period on the second week. On top of that I was angry and sad all the time, if I wasn't yelling I was crying. I had no sex drive, and that is one thing I always prided myself on , was having such a high sex drive. I have deciede to stop taking it, but don't know how long it will take to feel normal.... I don't know if this will help anyone, but that it my story.
