Hello! I'm on lutera combo birth control. I was on the sugar pills last week and started my period on the third day. I had my period for 4 days. I don't take the sugar pills but I'm very diligent and always start the active pill after 7 days of not having it. Today I took my first active pill and had unprotected sex. I noticed some brown blood afterward. Is that normal? Was I protected? I take my pill within the same hour every day.
