"i&#039;ve been on microgestin for 3 weeks. i started taking it on the 1st day of my period and it make my (normally very regular period) last for 8 days (it usually lasts 4-5)! for the entire time i have been very moody, bloated, retaining water, have had cramps, nausea, acne, breakthrough bleeding, everything. the whole time. i literally feel like i have been on my period for 3 weeks. i keep hoping that eventually my body will get used to these hormones. my doctor said it will take 1-3 months to regulate, but i don&#039;t know if i want to live like i&#039;m on my period for 3 full months.
