is it bad to what to have kids at an early age?

Temiekan
So, I'm 23 and want to be a mum really bad, but I don't have a job and I'm currently studying. Nearly all my friends are either having babies, trying to have kids or are married or getting married. Is it bad that I'm jealous because it's what I want? Is bad that I get disappointed when I don't end up pregnant?
My partner and I have been together for 5 years and he won't let us have kids u till we are financially stable and I have a job...I feel bad for being jealous that others have a great life and mine is somehow falling apart due to other family reasons. 
I'm just looking for some advice
