"i am 18 now i was on the lowest dose of trinessa for 8 months to regulate my period. i get terrible migraines due to irregular period and they get so bad i end up at the er so my doctor put me back on trinessa. i loved it. it gives me my period every month around the same couple days after a few months of starting the pill, my acne was all cleared, and i had 2 migraines in 8 months and no daily headaches like usual. the only cons are that i gained about 5 pounds which isn&#039;t so bad all birth control does this but i am also tiny for my age (105 pounds) and i was also a bit moody. but those side affects are a lot better than migraines which are not even bearable. i recommend this birth control. also my insurance covers the price every month."
