Fundal Measurement coming up small

[rach6122]

at my 20 week scan everything was perfect, no abnormalities everything in the right place etc, but sonographer said baby was on the smaller side. i went to see my doctor today for a check up and i measured at 22cm, although i will be 25 weeks on Saturday, she has booked me into go for another scan and now im really worried something may be wrong. has anyone experienced this?

Relax. Measurements are not an accurate way to tell anything. I was measured twice on the same day by different midwives. One said 25cm and the other said 28cm.
But it's good that you get a scan in case anything does come up! Most likely, everything is fine.
