I had my 20w anatomy scan today. Baby looks good and is measuring about 5 days ahead, weighing 1 pound. Everything was fine except they said I have something called partial circumvallate placenta. The dr told me this is common and not to worry, that it may resolve itself, and so to check I have another scan at 32w. Of course I googled it as soon as I left and there's not a lot of info on the partial version but the full one can be scary. Has anyone been told they have the partial one? How did it turn out?
