it's been a good few weeks (6/7/8?) since you last went running, so sadly I would say most likely no.
It's no problem to run in pregnancy at all, provided that it's something you've been doing before fairly consistently, but you have had a good break from it which was obv what your body needed.
Plenty of exercise you can do though, so don't feel you're doomed to couch-potato-land for the next 7 or 8 months!
WP is right as well, you will definitely know what feels right and what feels wrong - listen to your bod as it's really important...if it feels uncomfortable or just not right then stop. There are some hard and fast rules about exercising in pregnancy which I think will be on the earlier link (won't bore you all with them again!!).
and contrary to what your granny might say, aerobics/jumping up and down/squats/lunges won't make the baby fall out. If it was that easy I wouldn't be begging for gas and air in the delivery room!
I'm a total exercise geek so very happy to answer any questions. Hope you're feeling better and enjoying being pregnant. .
