What should my exercise be like in the two week wait? In preparing, I've been doing somewhat intensive exercise (weight lifting and light cardio one day and walk/jogging the other)that's not meant for pregnant women. I'm not sure what to do since I obviously will never know I'm pregnant in any 2ww. I don't want to slack in those two weeks but don't want to risk harming the pregnancy. I used to run marathons and have been doing my current routine for almost 3 months.
