When I last went to my OBGYN, I told her that me and DH were going to try for baby, and I was a little concerned about all the exercise restrictions once pregnant.
"Oh, you can absolutely exercise!"
"OK, cool, anything I should avoid?"
"Not that I can think of. Just whatever feels right at the time."
"So I can scuba dive?"
She rolled her eyes at me, "No, I'd say no scuba diving."
"Alright, then, mountain biking?"
She sized me up a bit. Sighed. Explained that first trimester MAYBE, since everything is still pretty well protected by the pelvis bones. After that, things get sticking out and more vulnerable. "But trust me, you may not even want to do anything. How about nothing that you're likely to crash with, ok?"
