19 and ttc

I know I'm a litttle young but I have lots of support :) iv had the baby fever before and now it's like I have it but it won't go away ! Iv been working with children since 14 . I went from a respite worker, to a nanny for a year , now im an aba worker , I live out on my own with my soon to be husband ❤ we have been 4 years so I'm pretty confident in having a baby, I'm also over weight so it's a little harder , I got testing done and they came back  fine so I can have a baby, still finding it hard tho , and suggested i could be doing ?
