Have a baby now or not 🤔

Okay, No judging please as this is something that is genuine and serious to me.

I am 20 years old, at Uni, I don't have any friends, I have been through so many things in life. I have lots of problems with my ovaries/womb and I am very scared that one day I will not be able to have children as the infection I keep getting causes damage to my reproductive system. I really want to have a baby and I have the right support around me, can support a baby finan2cially and have everything I would need and I would be a great mum to my baby. But I am taking into consideration that I'm very young and at University but this is something I want so much and I think having a baby would bring so much joy to me and my life. I literally have nightmares that being a mum will be taken from me as one day it could be, that's why I feel like I need to start now so that my chances are better as I have already had so many things happen to my ovaries/womb. If you wanted to be a mum so much and you knew one day that could be taken from you, would you feel the same as me? Or am I just thinking irrationally? I know it seems crazy, I just have a genuine fear that I won't be a mum one day 😔😔
