Been there done that. I know what you are going through. My sister and sister-in-law were pregnant and gave birth within 5 weeks of each other so then everyone turned to me and said 'when are you going to have children?'
I felt like screaming, people don't realise how much it hurts hearing people ask that question. All your life someone always has to ask 'what's next?'. Either, 'when are you going to meet a nice boy?' to 'when are you getting engaged?' to 'when's the wedding?' to 'kids? to 'next kid?' .
My MIL has a habit of everytime she calls the first question is 'babies yet?'. I ended up just not answering the phone for a while there. In the end I told my hubby to tell his mum to lay off or I would. She already has 8 grandkids but feels the need for more NOW!
I havn't told many people that we are trying because I didn't want their pity. The support I have received from the few I have told is enough.

Try telling a few people to quietly spread the word that you either don't want to hear their questions anymore or that you are having trouble conceiving. Or you could make a bit of a joke out of it by saying that you're quite happy to stick to dogs/cats/ etc for now.

I know the pain of having to hear the questions and to see pregnant people and wish that it was you. All I can say is best of luck and keep trying. Here's hoping to a for us both and soon.
