spotting on the pill

Barbara

Hi.

I started spotting last week, right before my placebo week. And i thought that i messed up something about taking my pills. So i decided to have my "period" and then see what is going on. My "period" was really light (they normally are quite light so it is not weird). Well after more then a week I am still spotting. There is really little blood and it is mostly like dark old blood. There is no chance I am pregnant so it is not implementation bleeding. Do you have some ideas?

We have holiday season at the moment in my country, so the first chance for me to go to a doctor is Monday. I think it is nothing serious, i just want to know what it is.
