Why people are sooooo selfish!!!

I need to vent this because people are soooo selfish I have 3 kids 13 8 and 20 months and as you can see there is a big gap between my kids is because I have fertility problems but now Im about 8 weeks pregnant but when I told my mom and my mother in law I was pregnant and some other people I was pregnant they said another one? After this one you will done right?

This make sad and uncomfortable!!! We are sooooo happy I'm happily married with my best friend and the best husband who support me mentally and financially !!!
