I am on microgestin Fe 1/20 and i am on the second week of my second pack, never missed a pill and still use back up protection (like we do unprotected but put on a condom right before he does ejaculate..even thougth i know that men secrete sperm throughout..) and i was wondering how long do these symptoms last? Becasue they are driving me crazy! I know i have no reason of thinking I'm pregnant, but it still freaks me out here nad there or at the very least has me worried for a good 5% of each day.
