If your fundal height has been consistently measuring 5-6cm ahead, and now all of a sudden at 30 weeks its measuring 2cm ahead. What exactly does this mean? For ex: at 27+4 fundal height was 34 cm. Now at 29+4 fundal height is 32cm. Does this mean she dropped? Which I think she did due to the constant pressure I have down there and literally everyone telling me it looks like I dropped.
