My LO was head down all the way through and stuck her head right down and was pretty much engaged from 30 weeks. I measured small for my last few weeks. I also had low fluid so they said it was a double explanation. She was average at Birth. Tell her to push for a scan to check, that is how they noticed my fluid problem. It may be nothing out of the ordinary but better to be safe.
I had a midwife appointment yesterday. I'm 36 weeks and my bump measuremenrs have all been ok for dates so far. Yesterday's measurement was measuring about 34 weeks. Baby's heartbeat was fine & he/she was jiggling about as usual, but my blood pressure was up a bit, so my midwife referred me for a growth scan to be on the safe side.
Had scan this morning, and baby's femur length, abdominal circumference etc are fine.
Bump masurements are not accurate, but if your friend is worried she should ask her midwife if she can be referred her for a scan to put her mind at ease.
Possibly the change in bump size is due to baby moving to a transverse position, making the bump stick out less.
