Advice?

Okay, so I have a little more information now. I had my son October 24th, I bled until about November 8th after having him.  I had unprotected sex on December 20th & December 23rd with my significant other. Now, because I don't know when my period will start, if it had came in the 2 weeks that I was bleeding from birth. I don't know when my period is supposed to come or when I have, or might have ovulated if I even did. I know, I know, it wasn't a smart to decision to do so. But does anyone know how likely it is that I could become pregnant again.
