So I had my OB appt today and he mentioned that on my ultrasound a couple weeks ago they saw some kind of "shadow" on my placenta and he wants me to have another ultrasound in 3 weeks. He said he wasn't worried about it and that he expects they won't find anything there on the next one, but now I AM worried! He said the baby looks great and that it is growing well and my uterus is measuring well... but what the heck could that placenta thing be? I thought about googling it but I know it will just freak me out more if I do. Anyone have anything like this before?
