Im 15 weeks, i have just got back from a scan, at my 12 week scan there was a high NT fold, so had further testing done, thank god the results came back clear. so today had to go and check baby's heart was ok, it is on my note the OB has written that my placenta is big, she ddint actually mention it to me.. so just wondering is a big placenta bad, will it cause a problem, or as im only 15 weeks will time tell?
