Running Momma Advice?

Allie • Pregnant with first Clomid/Trigger Shot Baby! Married, Texas, 30!
Hey! 
Any running mommies out there?! I am currently 26 weeks along in my pregnancy. My EDD is November 15th, 2016. 
I was a big runner before and ran 10 Half Marathons and 1 Full Marathon before I became pregnant. I have now stopped running because of the pressure, it's just uncomfortable for me. But I still do Camp Gladiator (Bootcamp outdoors) for an hour each time 3 times a week and feel just fine! 
My main question is, I'd like to sign up for a Half Marathon again after baby is here (I'm already getting the itch to run again! Haha!). Any advice on how soon after baby you can start training for a Half Marathon? I realize this won't be my main priority as baby will be and I have NO idea what the birth will be like for me. I realize that you have to wait 6 weeks after baby to recuperate and get an okay from your Doctor, but, I was just curious how soon after you had your baby that you started to run again or signed up for a race?
Thanks in advance!
