I recently had a miscarriage at 9 weeks and am now more concerned for my next pregnancy which I hope will be in the near future. Anyhow, I was exercising about 6 days a week, rotating step, weights and tae-bo. My workouts are vigorous but I'm used to it, but I am still wondering about the safety of the baby with all that bouncing around. Is it really ok to still do jumping jacks and jog and do high-impact. Any input would be helpful. Thank you.
