I was never asked this, but I was asked some stupid questions and had some stupid things said to me. There was a woman I knew from school, who was a little odd, and had never had a boyfriend. Even by nearly 30. I was first pregnant when I was almost 30, and had been married several years. She looked aghast when I told her, and said (whilst covering her mouth!) 'Oh my GODDDD, you've had sex!' 
I said 'well I am nearly 30, and have been married a few years, and own my own house and everything. '
She couldn't process that I had had sex - as when we knew each other at school, we had both never had a boyfriend, even by 16/17, and were still virgins, and were both outcasts at school and never in any cliques.
When I left, I moved on, and made lots of friends, and had my first boyfriend at 18. She never dated anyone and was proper puzzled when I said I was pregnant! Even though I was married!
I also had 'U not had that baby yet?!' from a really fucking annoying colleague of DH's every fucking time I saw her. Got on my tits it did. AND I got 'not lost that baby weight yet then?' from one of my parents neighbours. Said it 3 times to me - in the first 4 WEEKS after I had had my first. Got to the point where I started going into their house via the back door/back garden so as not to encounter this neighbour!
People are such arseholes to pregnant women/women who have just had babies.
