Newbie and needing help?!

Ra

I have wanted a child (of my own) since I was 13. I'm now 19 almost 20 and ready to TTC. My fiance is 24 and has a beautiful 6 year old daughter. We have finally settled down in a new apartment. Any help on how to get started on all this? Like what do I need to do? what do I need to get? Helppppp 🤷‍♀️.
