I am 25, have been with partner for 4.5 years trying to get pregnant is this too soon and too young??

We have a house and both have full time steady good paying jobs, we seldom go out, once every months would be a lot, we feel were are ready but how do you know for sure, I dream about being pregnant or having a child of my own most nights. I should also mention i had an abortion 6 years ago and have punished myself everyday since
