I haven't gotten pregnant like that myself, but it is definitely possible!

I don't think it is strange that you would want to be pregnant, I honestly think if my DH and I were going to separate (have been having a rough time lately, but slowly getting better) I would be tempted to get pregnant first, lol, we make wonderful children and I don't think I'm finished having babies yet. It might not be the ideal situation...but I would definitely be tempted.
