Is my baby not growing? :/

Ka

Hey guys...this may be a dumb question, but I am 13 weeks today and when I lay down my stomach is completely flat. When I feel around by my pubic bone, its just squishy, not firm. I cant feel my uterus. I thought by this point it was supposed to lift out from under my pubic bone. I do have a tilted uterus so maybe thats why I dont feel it? Im just paranoid my baby isnt growing in there. 😂 thank God I have an ultrasound this Saturday.
