Having a period and pregnant

Anjil • 36 married 4 kids
So my af was due 1/7/16 and I got a positive on 1/5/16 and tested both days after. Now today the 10th I started spotting and slightly bleeding. No pain or cramping and no blood clots. I have never had a period being pregnant and wondering if this is the first. Anyone have a period while being pregnant?
