Any Exercise enthusiasts out there?

With my first two pregnancies I didn't exercise at all.  With my third I ran up until 6 weeks when I participated in a half marathon and then stopped.  With this pregnancy I have been working out pretty hard core and don't know how hard core I should be.  I don't go to the doctor until the 10th.  Are there any other hard core workout enthusiasts out there that can tell me your thoughts?
