"i had severe preeclampsia st the end of my pregnancy that did not go away after birth. my dr prescribed this birth control because it doesn&#039;t raise your bp like combo pills do. so i waited 7 weeks postpartum to start the pills. as soon as i started them i started to bleed and i didn&#039;t stop bleeding for 8 straight weeks. apparently, this happens to many people and it&#039;s the lack of estrogen in the pills that makes it happen.. i didn&#039;t have too many other side effects from these however. most bc pills make me crazy.. these didn&#039;t so at least there is one good thing about them. but i did stop taking them. now i&#039;m going to start tri linyah.. wish me luck."
