Nervous about Tuesday.

I have my 37 week appointment with sonogram coming up, but I have now gone 2 months with zero weight gain, and last belly measured right at the bottom line of the 33cm at 35 weeks. I know my little love is okay since as I type she is on the move getting her daddy's attention with her acrobatic skills. I'm just worried about what happens if I fall below the standard measurements, and what the doctor has to say.

My family is even made several comments about how much smaller I am this pregnancy, were the last 2 were always in the 90-95%.
