So I had a follow up ultrasound today due to my low lying placenta. The placenta moved up so i dont have to worry about that anymore thankfully!! Baby was only measuring 21 weeks and 6 days! I am 26 weeks and 2 days, so thats at least a 4 1/2 week difference! I know that the u/s can be up to 2 weeks off, but it still seems like she is too small! The doc isnt too worried about it as I have small babies, but I dont remember the other 2 ever measuring so far off! Im just super nervous! I dont want to be worried if the doc isnt, but I cant help it!
