lesbian couple starting family

Christina
Hello everyone, 
We are a lesbian couple that have been together a totally of 5 years. 3 of them have been LD, we changed that in 2015. I popped the question last year and plan to get married in September (excited!!) any how we are like any other young adults trying to make a living, and the idea of starting a family overwhelms me (money) trying to find the easiest, cheapest, smartest way to go about it any suggestions?!
