Activities and trying to conceive

I'm currently trying to conceive and In the lovely 2 week waiting period. I am wondering about continuing or the need to discontinue certain activities. I typically do bikrim yoga, which is hot yoga in a 102 degree room for 90 minutes, I know once I am pregnant I will not continue due to the heat, however I am wondering about the waiting time. I don't want to stop if I'm not pregnant but I also don't want to hinder any conception. Also, how do y'all feel about getting massages or going in a sauna room, etc. during waiting time?
