with my 1st child we had sex right up to to day she was born. In fact the Doc incouraged us to have sex more often at the end because she was due the 7th and waited till the 27th to get here, lol. I enjoyed doggie and me on top and spooning, and as long as she is not complaining, don't worry about being too ruff. That last month of pregnancy was wonderful lots of ruff doggie style sex, hummmmmmmmmmmmmm
