I haven't had an ultrasound yet, but I thought I was 6 weeks along when I saw the dr last week, then he said my uterus is measuring more like 10 weeks...and that a large fibroid is a possible cause (among other things). Has anyone had a fibroid present like this early on? I'm hoping my dates are just off, because if it's a fibroid it's quite large already! I can feel that my uterus is already about halfway to my belly button, I've gained about 5 lbs already and most of my pants don't fit. Thanks for your input!
