Hello, I am new to the combined pill and started taking Marvelon. I had nearly finished all three packs with only a week left although decided to switch to Yasmin due to bad side effects. My doctor said it was fine to go straight onto a new pill without finishing my old pack. Although, on the second day of taking Yasmin I started spotting and eventually got a light period the next day. This lighter period lasted around four days (normal) but it has been spotting ever since. It's been ten days and now it isn't really blood, more like a light yellow-brown discharge like once or twice a day. Should I be worried?
