CrossFit and Pregnancy

Any ladies out there do CrossFit? My wife and I have been on the road to IUI the past few months to start a family. Well, the time has arrived and we are scheduled for IUI the week of september 5th. I am incredibly excited, but also nervous about doing crossfit during the very early stages, including possible conception and implantation. Any advice for me? When you knew you were going to be trying to concieve, did you go to the gym, how often, did you scale? i am less worried about crossfit once the pregnancy is confirmed, but beforehand is different.
