I took Loestrin Fe for two months, then switched to Microgestin 1/20, the generic version of Loestrin. I had no problem with the first pack of Microgestin, and I'm on my second pack of it. It's been 2 days into my brown pills and no period! This has never happened to me. During this second pack I had brown discharge for about a week during my active pills... was this my period? I took several pills this month a couple of hours late, and my first pill of the pack a day late. I've also been urinating quite frequently today and my breasts do feel swollen... is this normal on Microgestin?
