"my insurance changed my prescription from otc lo to trinessa.  trinessa is effective in the sense that it has prevented unwanted pregnancy, however, for the last four months i have been on this medication, i have been feeling bloated and nauseous every single day.  for the first two months, i would take pregnancy tests because i thought i was pregnant.  i have changed the time i take this medicine from early morning to taking it at night before bed; i make sure i don&#039;t take it on an empty stomach. nothing i have done seem to alleviate this problem.  this has not help the situation in the bed room.  i have this medication change to otc lo and just paid the high copayments monthly."
