21 and want a baby

Hey guys, so when I was 21 (last year) I found out I was pregnant. I had always had a plan for having a baby which would include not having a baby until I was around 27. But I fell in love with my baby, as did my husband. However, I had a miscarriage. After that my hubby wanted to try again but I was still not over the death of our child. Now a year later, I have decided to try again. All I want is to have a child with my husband, so desperately. But as I tell my friends about wanting a child and others my age, they don't think it's a good idea since I'm so young. They tell me I still have a lot of life left to live. Has anyone else dealt with this?
