How often do you work out?

Kelly
I am wondering how often everyone goes to the gym and what sort of exercises they do. I'm about 20 lbs over where I should be, product of a miscarriage and some depression earlier this year. I had intended to get the weight off this summer, but I discovered I was pregnant two weeks ago and have been very bloated since then. I am 6 weeks today, and I'm just doing 30-40min cycling or elliptical 5 days a week. Is that enough? Should I be doing more?
