"I&#039;ve been on Trinessa for over 7 years, and I&#039;ve had no problems at all.  Very rarely, on weeks two and four, I&#039;ll get a blemish, but I barely even notice it.  No cramps, regular period to the 28th day like clockwork, and no pregnancy.  I stopped taking it for about 3 months and didn&#039;t get my period for the whole time, but once I started back, it went right back to normal."
