abnormal uterine bleeding
"I've only been on TriNessa for a month now but so far I'm having mixed results.  I decided to go back on birth control after a 8 year break (my husband had a vasectomy 8 years ago).  I had been looking into NovaSure due to extremely heavy periods but decided to try the cheaper route first.  I used to be on Ortho- Tricyclen before my second son was born with no problems that I recall.  I asked for the same again but was given TriNessa which I assumed would be the same.  Almost as soon as I started, I've been experiencing night sweats, slight weight gain (about 5lbs), and breast soreness.  So far my period is lighter though so I guess it worked for that.  I'll give it another 2 months and see if the negatives go away."
