CrossFit open during early pregnancy?

How crucial is the first couple weeks for doing intense workouts after a positive test? (No heart beat yet). I have the CrossFit open competitions the next two weeks (been doing CrossFit for over 5 years) and I don’t know if I should bow out or not and I can’t reach my doctor (I have had 1 live birth and 1 stillborn and 2 miscarriages) so now I don’t know what to do! Help! ARE THERE ANY DOCTORS OR NURSES ON THIS GROUP
