This is my 4th week of taking birth control pills and My second day of taking the placebo pills. So far I have been having light bleeding. Is it normal to have light bleeding while taking the placebo pills ? Or will my flow get heavier As the days go by? I've been on birth control for a month now. I have also been taking it every day and at the same time every day. I'm curious due to being new to the whole thing of taking birth control. Thanks.
