So today I went in for my apt and the dr said my uterus is measuring between 15 and 16 weeks. We found baby right under my belly button. I'm 11 wks 5 days, we had an ultrasound at 6 weeks that dated baby. They are having me come back in two weeks to check where it's at and to see if it has gotten bigger, and if so they will do another ultrasound to check my dates and for a possible other baby. During my ultrasound at 6 weeks they couldn't see the whole left side of my uterus or even my left ovary because babys sack was blocking. My dr said my uterus could just be tilted forward or that it could just be large because this is my 3rd baby.
