Hi:
unfortunately, this could possibly just be the way your body is reacting to the pill. I am sorry, I bet this is very frustrating. Spotting is very common the first couple months on the pill, and it could be that switching is causing you problems. I would give the pill you are on right now a little more time, just so your body can get used to it. Chances are that the problem will get better with time as you are regulated by the hormones. If there is no improvement, then I would consider another form of birth control, like perhaps the nuva ring. It is just as reliable as the pill, only different. I hope this helps. Good luck!
