People really don't know when to stop talking when faced with a heavily pregnant woman..
I have severe SPD, making me pretty much immobile. DH went out for a runabout at the park with some mates today and came back saying "today I am aching more than you could possibly be hurting.."

Random woman I know: "I take it you haven't had the baby yet, then?" (I'm 39+3 and visibly pregnant)
MIL, on the phone: "I thought you were calling me to tell me that the baby has started" (only a couple of hours after I told her that we were going to keep things quiet and low key)
"any signs yet?/still preggers?/bump still here?/have you had the baby yet?" from about a million people every day, even after I reassured everyone repeatedly that I promise to let them know when I have given birth. When I I say that, I get "but you might be too busy to let me know". yes, then I would be too busy to reply to your constant stream of texts, too.
"are you sure you're due already, you're tiny!" after 3 months of "oh god, you're huge!"
and of course all the horror stories about labour and birth and having babies... no wonder I'm constantly pissed off and willing to kill someone at the moment...
