"i am 21 years old. i started trinessa when i was 18 for birth control. the pill was wonderful, and i stayed on it for about 8 months or so. i stopped the pill for six months, but because my periods become irregular i started the pill again. this time i&#039;ve been on it the longest probably a year and a half or 2. i think the last 6 months or so have been hell. i experienced cramping, bloating, and nausea starting on week 2 of the pill pack. close to week 3 i have a series of migraines. the headaches were too much for me. i stopped the pills and am now on loestrin 24 fe. i just started week two, so i don&#039;t know how well these work. overall trinessa is an effective pill. i think my body just got tired of it. i hope my review helps!"
