Is 25 too young to be pregnant ?

25 y/o RN engaged to my 25 y/o fiancé who’s a mechanic . I found out 3 months ago I was pregnant . My fiancé and I bought our house last July and are completely independent from our families. We both have successful careers. We decided to tell our families at 12 weeks we were pregnant and shortly after our engagement. My fiancés family was extremely excited, and so was my mother. My parents are still together, but my dad was very upset and angry. Not only was he upset, but so was my grandma and uncles. They think I’m too young to be having a child and think that I’m ruining my life. I’m in school for my masters and financially I believe my fiancé and I make upper middle class money . Are we too young ?
