I measured funny, so I'd estimate fetal weight and fluid levels.
If the measurement was accurate, I'd try to feel if it were baby or fluid.
Check dates, when was the first positive pregnancy test - early fundal measurements, ultrasound reports, family history, etc.
Offer ultrasound, talk about when I'd consider an ultrasound to be indicated - when is it an offer and when I'm requesting the information to best care for you.
Consider diabetes screening, including doing the 3 hr. GTT or random blood sugar screens at home with the monitor.
Rh and blood studies? Is she Type O, or Rh negative?
There are quite a few things that lead to polyhydramnios - rule that out and a lot of things look better, with poly you've got lots of maternal or fetal issues that could cause it (and lots of benign things, too).
Most likely, big baby, normal fluid...I'd say dating is off.
OK..here goes...first, the midwife measured the same as what I've been getting, currently 35 at 31 weeks. She double checked my records from dd's pregnancy, and at 31 weeks, i was 30. She palpated, a skill for which she has an excellent reputation (very experienced midwife - direct-entry turned CNM, with hospital, FS birth center and homebirth expereince) and her clinical opinion was that the fluid was normal but that the baby itself is very large. She also said she sometimes sees larger measurements in women at this stage because babe is still up high and floating, but in my case, babe's head is well engaged in pelvis, with body curling up all the way around, and bum under my ribs on right side.
I do have PCOS/history of blood sugar issues, which have been well controlled, have been doing multiple daily sticks and my numbers are good - highest am reading 91, highest 1 hr after meal reading 126, so no problems there. I do very limited dairy as a result of this, also limited carbs, etc...
Dates are spot on, charting for nearly a decade with lmp on march 28(preceded by 3 days of BFN tests - I'm impatient, lol!, so it was definitely a real period), clomid days 1-5, ovulation (severe mittelshmerz and .7 degree temp spike) on cd15 - april ll, started testing on April 19 (8 dpo) got BFN's on april 19 and april 20(again confirming that i was NOT already pregnant and that my lmp was not a "false" period), then got a faint BFP the 21st(10dpo), which darkened over the next couple days. Timing of morning sickness also conincided, as did quickening, which happened during week 20, not super early like you might expect if my dates were behind.
So really, dates are spot on. I'd bet anything.
You ask about blood type. I have not heard about anything relating to blood type causing big baby? could you tell a little more about this? I am B+ and dh is A+.
Thanks for your thoughts!
