Hi Congratulations! Did you get the sonogram done then? We are confirmed pregnant? :>)))) That's great.
You can still remain active unless your doctor tells you otherwise. In fact, it's usually best for you. You can run still. When you get bigger, this will be harder and you'll likely not run much in your last trimester and maybe do more of a run walk. It's hard to get that belly around once it is large. But early on especially, that baby is tiny and well insulated. You should be able to do most of your regular activities! Talk to your doctor of course. Anyway, when do you think you are due?
