This month i decided to change the time that I take my birth controli (Microgestin Fe 1/20)from 6:45 pm to 8:30 am. I have taken every pill between 8:00-8:45 since this month started and I haven't missed any pills. However, I have experienced a very very light breakthrough bleeding during my second week. I am just worried because I know that this can be a sign of pregnancy, but considering I've taken my pills on time everyday, this shouldn't be an option. I was just wondering if anyone else had experienced something similar.
