I was on cyclessa for about 4 months when the nurse practitioner switched me to modicon. I had a horrible reaction from the increase in dosage and when I got out the hospital, that next day I started my cyclessa again and threw up all night long. Now I am not taking anything and my period is on...AGAIN and I just got off of it last sunday! I am so frustrated. I know I am supposed to have breakthrough bleeding but this is a bit rediculous. Another question I have? Does this mean my body won't be able to handle Oral Contraceptives anymore? Is there a pill that rarely causes nausea over others? Advice would be awesome :-D. Thanks
