"i have been on ortho tri cyclin lo on and off for 2 years now and haven&#039;t had a problem. my insurance switched me to this medication and i&#039;ve had nothing but problems with it. nausea and headaches, my periods have been up to two weeks longs and i&#039;ve had much pain during the time of them. you should try it for yourself but for me it wasn&#039;t good and i took it for 4 months. the doctor had me stay on to see if it got better and it hasn&#039;t so i was forced to switch to something else."
