I have been on generess fe birth control pills (low dose) for about 5 months and no complaints. This month I started bleeding in the middle of the pack very light for about 2 days. Is this my period or just spotting? Now I have 3 green pills left and boobs are sore, this has never happened to me before. Will I get my period again on the brown pills? I never misssed a pill and take them at the same time to an hr or two later sometimes.
