I didn't really change things much during either pregnancy and didn't get warnings about exercise, more like encouragement to exercise moderately.

With ODS (who is PG per testing), I walked some, especially once he was "overdue." I tried using our elliptical machine, but kept getting really weird feelings while using it and gave that up. My diet was pretty good, lots of whatever fish was "acceptable" at that time, but certainly not perfect.

With YDS, I developed horrid pains, which later turned out to be a hole in the ligament that supports the uterus. So I got some fun times at physical therapy.
