4 weeks and 6 days today

Chrissy
Hey everyone! I am 4 weeks and 6 days today! This is my first pregnancy and I'm so worried because of my age, and the potential risk factors. I'm 41 but as my doc says I'm really healthy and the only risk is my age. So that's a god thing. I'm just wondering why I don't seem to show just yet? I'm a healthy weight to begin with so it could be that and that it's my first. I'm just concerned. 
I don't have my first ultra sound for a while now, end of July and I just hope and pray my little one makes it that far and I have a very healthy pregnancy and baby!
Thanks ya'll!
