Jogging at 39 weeks?

Sascha3

My SIL is still jogging 2 miles twice a week and is due next week!  Such motivation...is that even safe?  I haven't stepped foot in a gym and have only gone on one walk.  I do stand, squat, climb ladders, etc for 8 hours a day without a chair break or place to sit, so I am moderately active.  But jogging??  Not going to happen.  I do plan on going back to a light all over weight training class called Body Pump for arm and leg strength, but no cardio besides my 30 minute walk that I plan on taking one of these days.
