"i have tried many pills and this one was better than the rest but i am switching because i get terrible migraines. on this pill i was getting 16-20 days of migraines even though this has the lowest, constant dose of estrogen. multi-phasic pills gave me 20-25 days of migraines. i switch to an intrauterine device and had 1-2 days but i don&#039;t want to deal with the cramping again so i am going to try something else. good birth control but bad for migraines."
