Probably not very good at all. I don't think it could be possible, but, I'm not a doctor and I don't know for sure. I'm almost 53 and I've been in Menopause since the age of 46. I can't imagine carrying a baby around in my body at this stage of the game.
Go to your doctor and have a hormone level check. There have been plenty of pregnant women who thought menopause was the end. Babies from this event have been nicknamed "cabooses" or oops..
