Pregnant and confused

I am 19 and my SO and I have only been together for a little over 4 months. The teen groups are too young for advice like this. I found out I am expecting a little jelly bean last week and am due on August 14, 2018. I am not upset about the baby, actually very excited. My problem is that I don't know what to do with this relationship. He always tells me that he is head over heels in love with me and wants to move in together ASAP. I appreciate him going out of his way to take care of this baby. I just don't know if I am personally ready for a super dedicated relationship and to just move in together because we are having a baby. I do love him and he is my best friend. It is just so much! I can't tell if I am just getting so annoyed all of the time because of hormones or what. He does keep rushing me and telling me I need to be making all these choices right now so he knows knows what to do. I told him to get a job and we can go from there. If I decide to move in together he would be moving to Denver CO from Seattle WA. I came down to visit family for christmas and decided to stay since I have the most support here and much better doctors. I am just so confused and I don't want my baby not to have a daddy. I am just scared things won't work out. . . Any advice is the best advice. Please help :(
