Im so stuck and idk what to do

I have two kids and i have always always wanted 3. I know i want 3. But i also want to do uni and work. I love working and as much as i love being a stay at home mum i can't wait to work.

My problem is idk if i should have my last one now my 2nd is 5months old. Or if i should go to uni. Im 22 and feel like im running out of time for uni. But i know if i start im not going to have a 3rd baby, and im scared im going to hate myself later.

My inlaws are very money driven and constantly make me feel like a shitty person, mother and wife for not doing anything with my life as they dont see caring for kids as anything important

There parents raised my husband while they were studying and working.

There always riding my husband about me and how usless i am and its taking its toll on him he is behind me 100% but i can see how much it hurts him and how worn down he is from the arguments. So now i feel selfish about wanting another one.

Im just so stuck and lost. I want my husband to be happy im his rock as he is mine. But i also dont want to give up what i know i want. So idk what to do.
