Two periods one month?? Help?

ca

So the last time I had sex was January 2nd. My period was January 11th-15th, so definitely not pregnant. My next period isn’t suppose to be until February 9th but I’ve been on a very light period/ spotting since around January 30th. It’s only old blood and clots so no new blood. I know sometimes Ill skip a period if I am extremely stressed but I’ve never had more than one period unless I’ve taken the pill.

I have not been on any kind of birth control either.

Anyone have any idea what’s going on? Should I go to doc? Could it be because of stress? (I’m going through a pretty rough breakup currently)
