Conceiving same sex relationship

So this post is to any and all same sex couples (preferably females) who have started a family together. Me and my fiancé are trying to take the steps into making a family together and I don’t know what the best and easiest way is. What do you guys recommend? We don’t have the money to get a sperm donor from a sperm bank, and I want it to feel natural. I’m 22 years old and she is 33 and I will be the one carrying the child. Have any of you gone outside of your relationship and slept with someone else to get pregnant or what do you recommend. Just looking for advice here because I have no clue where to start.

Picture of us for attention 💕
