Just start slow and watch ur carbs too. You can easily not gain anymore. You can do 1 mile in the morning and 1 in the evening.

I need to start then because I already gain 34 and only 6 months I look like a whale @kandice_stedman86

Walking is great excercise. Last pregnancy gained 60lbs 30 by the 1/2 way mark, this time only 10lbs at same amount of weeks I walk 2 miles a day.
