Fundal Height

Katherine
has anyone else measured consistantly behind in FH? I started at about a week behind at 23 weeks, but the gap has been growing. At 30 weeks, I was measuring 27 cm and today, at 32 weeks. I was still at 27 cm. My doctor's office is pretty vague - they say it could be because I am on the tall side (5'8") and it's my first child or, it could be something more serious, esp. bc I am not gaining any weight (only 5 lbs overall). 
I've had an ultrasound scheduled since my anatomy scan to make sure my placenta moved so the Dr isn't going to order another in the interim. I'm trying not to worry bc Baby is active and the heartbeat was strong at today's appointment, but it's hard.
