I'm pregnant but now I'm bleeding?

I just recently found out that Im pregnant not too long ago. I started bleeding three weeks before I found out I was pregnant and everything was fine. It was more like a here and there type thing, very very very light bleeding but now exactly three weeks and two days later I'm bleeding again. Its light pink also but its not so heavy neither, I've got an past of cysts that seem to grow on my left ovarie. Could that be the reason? I am only two months along, I'll be three very soon. Any suggestions, could it be impending miscarriage although I have no intense cramping? Well! Let me know what you think, I could use the advice before I head to the doctors.
