How do you deal with people always asking when you're going to have kids?

I've just been told I have endometriosis, my partner and I have been ttc for 2 years.

We are slowly going through the process of finding out what's wrong and what we can do about it (we've chose to only tell really close family) my sister (who is going through something similar), my partners mum (who knows the doctors personally and knew who we should book into) and my mum (Just to keep her informed, well because I'm her child) 🤷🏽‍♀️

But my grandma always asks when I'm going to give her a great grandchild and my friends always ask aswell.

I feel really bad when I get upset but when you are asked everyday it gets to much.
