Bump is shrinking???

UPDATE: Baby is in fact very small. She dropped from the 40th percentile to the 6th between my 24 week US to today (32 week US). I now have to get a US every week to monitor her growth.

Really worried ladies. I’ve noticed over the course of approximately 2 weeks that my belly has been looking smaller then it was before. Does anyone know why this could be? This has never happened in my 5 other pregnancies. I know dropping can make it look smaller, but my stomach itself looks a lot smaller. Left was at 27 weeks and right is at 32 weeks.
