"after switching to trinessa after years on triprevefem without issue, i experienced side effects that were like every symptom of pregnancy. i started having unusual menstrual-like and lower abdominal cramps, indigestion, bloating, heartburn that did not go away. i thought i had gained 10 pounds. my breasts jumped at least cup size. i was dizzy and exhausted with intense headaches despite getting plenty of rest. pregnancy was a minuscule possibility because i had been using backup methods without fail. my period came a few days late and i immediately switched back to triprevefem. all of the symptoms went away except enlarged breasts, which i certainly can&#039;t complain about. my advice: pay out for brand name for some piece of mind and health."
