TTC/Period after Miscarriage

Hey, so I am 19 years old, currently in an amazing relationship. I got pregnant and found out the day after Thanksgiving 2015. I was happy about it and so was he, we were ready for this new challenge and fell more in love because of it. We were ready, no matter what anyone says. Well, the last week of December 2015 I was spotting brown a little each day, then on January 3rd 2016 I miscarried in the ER. We were both devastated, as we still are but are finding peace with it slowly. 
Anyways, I was bleeding from the 3rd through the 13th, and today being February 15th I still haven't gotten my period and it's a week late. I'm just wondering how your cycles resumed after miscarriage and if it's possible that I am pregnant again so fast because we have been trying. We want this.
So when after the bleeding stopped did you get your period? Because I ovulated (used a OPK) around January 24th, and I haven't gotten my period yet. I've been pregnancy testing and they are all negative.
