Hi i am currently in my third month of taking tri cyclen lo and during my third week of pills i started bleeding not heavy its light but it gets heavier. I am suppose to start my placebo pills this thursday which is tomorrow, but i am wondering why i am bleeding. Is this breakthrough bleeding at the 3 month period or is it something else. I take my pills everyday i havent missed any but i am jus wondering what is going on. Is there any way for me to stop this unwanted bleeding or do i have to wait till i start my white pills which is a week from now? Please help i am very worried.
