Exercise and TTC?

​My husband and I are on month two of TTC and since there's a lot of things going on in my life right now so I'd love to get back into running to help calm my nerves.
I've heard that when you're pregnant, if you're already a runner you can keep running. I used to run a lot but haven't in about 10 months... 
​Are there any known problems with running (very slowly) while trying to conceive? 
​Best of luck to everyone on their baby journey :)
