My MOH has this, she has an OB appt this arvo, and they have recommended for her to have amniotic fluid drained as she has an extremely excessive amount. In her first pregnancy she had the same, her DS was born 8 weeks early (around 5.5 pds), and the condition is a bit worse this time. There are varying degrees of how serious it is, so your OB/Health Professional should be able to give you more info. She also looks like she is ready to pop, but she's not due until Feb.
I'd say you'll be closely monitored to make sure everything is going ok, good luck, and relax as much as possible!
