What was your AFI? Its a number... "normal" is between 5-25 cm.
I was diagnosed with too much fluid this last pregnancy- I was measuring 40 cm at 33 weeks.
I went and got an ultrasound and all was well with the baby but the estimated fetal weight was 6 lb 15 oz at 34 weeks. Too much fluid can be due to a big baby... my AFI was usually in the 31 cm range (which is high)
there is nothing one can do to reduce it naturally.
It can also be a symptom of gestational diabetes. But most likely it is do to a "bigger' baby or due to nothing...
I went into labor at 39 weeks, it started with my water breaking. I leaked a lot of fluid, obviously, but other than that nothing else was wrong. I did end up with a RCS for a posterior 9 lb baby (failed VBAC) but that had nothing to do with the fluid
the only worry is that too much fluid can increase your risk of cord prolapse or placental abruption, but those are rare occurances and most likely all is well. If your AFI were some crazy number, like in the 40s or whatnot, that would be more of a concern.
