First Pregnancy

Hello. This is my first pregnancy and it wasn’t planned. I’m excited but nervous. I found this out last last Friday. My first appointment was last Wednesday and I found out I was two months along. Any advice? I don’t have anything planned! I know it’s earlier but I feel like this time is going to fly by and I want to be prepared. Should I make a list of stuff I need or should get. Where do I start?!
