20 and dying for a baby

I'm only 20 and I want nothing more than to be pregnant. I was pregnant with our first around this time last year when I was 19 and we lost the baby in april. We're not married or engaged, but we live together in our own house, have our own jobs, car, pay our own bills, etc. I'm not in any hurry to grow up, I just want to be a mother more than anything ever since we lost our little one. We haven't used any contraceptive since we miscarried, but not really "trying." Is anyone else in this same boat? I wouldn't say that we were perfectly financially stable, I know babies are expensive, but we have always found a way to things work.
