"i was on mirena after my son was born. i kept having bad side effects for over a year including getting very bad ovarian cysts. i was originally on microgestin 1/20 and i did notice a big improvement with the cysts and how bad my cramps were during period. then i started to get a bald spot on my scalp. contacted dr just to be told that it&#039;s normal and to give it a few weeks. this was like 6 months after starting pill. dr then changed it to 1.5/30. hair did start growing back but i couldn&#039;t wear my hair up for several weeks. i haven&#039;t gained any more weight than before starting the pill but am struggling to lose weight. i&#039;ve read tons of bad reviews but for me this is 10 better than the sides effects i had from mirena."
