So I have been on microgestin fe 1/20 and i'm on my last pill of the pack. I understand that for the first 7 days use protection, but my fiance and I decided to use back up protection for the entire month, just to be sure. But, these past two weeks, we have tried unprotected here and there-not going all the way, but I also understand that men secrete sperm throughout it all. I have taken my pills correctly, at the same time on the dot every day. But can someone please more thorougly explain the effectivness to me, please? And am i safe from having a kid when we did play a little unprotected?
