ah I'm going to go crazy I have a 3 month old n I already want another one. what is wrong with me

I was like that also it went away and now it's back and I don't dare tell my fiance that I want another he hasn't asked yet but we call each other fiance and he got hurt n hasn't worked and I'm only working part time so definitely not financially ready for another at all!!

I just had my baby, 2 weeks ago, and I miss being pregnant.
