when you are married and young people assume you must be pregnant...nope.
then you get "when are you going to have a baby?" which is hurtful - it assumes you got married to have kids (uhhh... nope), and that you are both fertile (at the time, that was another nope), and that you want to have them immediately!
I had 10 years of that, while trying to come to terms with being infertile. the worst pressure came from our parents who knew I couldn't have children - including "but babies are so cute, and you'd be a good mother!" and my mother knitting a whole box of booties and posting them to me! (helloooo ebay!)
then we divorced, I met my fiance, got pregnant.... (looks like the doctors were wrong about that infertility thing!)... and as soon as the poor kid was out of me I was asked "when are you having the next one??!" and I replied with "well certainly not when I'm sill bleeding from having this one!"
Got pregnant, "it's too soon! haven't you heard of condoms?"
miscarried, "oh dear!" "it's not like you lost a real baby"
then we were back to "when are you having another one?"
a year later, I got pregnant again.
"oh! did you not want a gap between them?" "it's not fair to your eldest!"
and the prizewinner 3 days before having the caesarian (for medical reasons) was "maybe you'll take more care with contraception this time?" (that one still stings, my baby was very much wanted and longed for, thank you! he's 6 days old today!)
so I'm expecting "when are you having the next one?" to start again soon!
I developed a rude reply or two years ago when I was told I was infertile - "I'm sorry, I didn't realise my uterus, sex life, and medical information was your business"
or the short version "my uterus, my business."
