Fundal Height?

[Pansy]

Is fundal height an accurate tool for measuring your baby?
I will be 21 weeks tomorrow and measuring 16 cm.
I have gained 7 lbs so far.
I still feel really tiny. But my dr doesn't seem to think fundal height is a biggie.
I just want to start looking pregnant!!!
Everyone is in shock when I tell them I am 5 months pregnant.
I have read that fundal height should be around how many weeks you are (I.E. 30 weeks,30 cm). How is everyone else measuring up?

im 4cm bigger then the amount of weeks i am, i was worried about it but so many people have told me that fundal height aint that accurate, you should keep an eye on it over a few weeks, the baby may have a growth spurt and you will catch up

hope this helps
