Ahh uncomfy! My bub was engaged from about 21 weeks, and it's hard to get things done some days hey. I have no idea when you'll go into labour, some babies can be that way for weeks probably, but that might not be the case for you...Like Trillian, in light of your history, I'd be surprised if you made it to term too. But you never know. Hang in there!

(Just an aside for an already engaged bub, they can come in a hurry, so if your bag's not already packed, perhaps do that...)
