After a miscarriage and a normal period have you ovulated?

This may be a dumb question, so I apologize if it is, I'm just curious.  I had a miscarriage Nov 17th and I was 8weeks. Since then, I have had a normal period dec 14 and jan 10th. If you have had a normal period, does that mean that you have ovulated? Just curious our chances of getting pregnant again, and not sure if it takes a couple of months? I took ovulation tests when I was ovulated this previous time, and couldn't find a positive.
