Is it right for me to be wanting a family ?

I’m 17 years old and I’ve been with my boyfriend for a year and 9 months, I love him so much and I do see myself with him in the future, but is it normal to be wanting kids ? I don’t really want to have a baby but sometimes I think I do, I want to wait until I’m at least 25 to have children, but I just crave having a baby, waking up to my child, looking after and playing with it, holding my own child that me and my boyfriend created together...I know it’s sounds weird that I’m young and all but is it normal to think like this ?
