Hi I've been on birth control pills for four months, for the first two months I was on Beyaz then this is my second month on Microgestin Fe 1/20. Yesterday I had light brown spotting that only lasted a day so far. Is this normal? I still have 9 days until my period is supposed to start. Please help! Also every month so far I have had a random day or two of spotting but I thought it would stop after the third month! Thanks!
