hi, Just my opinion, but I would have to sat that a VBAc should still be an option. I'm not entirely sure but did you see a perinatologist...can't remember what you said. I'm sure that an OB will have to go along with the "decision" of the specialist.... with my 5th baby (born in Feb.of 07) I developed polyhydramnios. At 38 weeks I had a c-section (my first cs after 4 vag. births). At 33 weeks, during an ultra sound to check baby's postion, my doc. discovered a 10cm abdominal mass in the baby. We didn't know the sex of the baby but my doctor said most likely we have a baby girl who has an ovarian cyst due to circulating maternal hormones. We went to a perinatologist who confirmed that the baby was a girl with an ovarian cyst. The polyhydramnios developed over the remaining weeks, after the cyst was discovered. My doc did not immediately insist on a c-section. She was willing to wait and see if a vag. birth would happen. Thing is, I had always been induced. And in this case, with the baby so high, there was no way I could be induced. But I have to admit that I was very concerned about pushing out a baby with a 10 cm fluid filled cyst. None of my babies had ever dropped before birth, I never went into labor on my own, even after waiting 14 days passed my EDD. And this baby was no exception. She kept floating, turning from head down to head up in minutes. So, I consented to the c.s. The hospital is 40 minutes from our home. My doc. said she was concerned that the cord would drop, or the baby's arm or leg. And I just wanted the baby to be born, so we could "deal with" the cyst. I'm sorry if I haven't helped you at all. I just wanted to share my experience with polyhydramnios. By the way, the cyst in my little girl disappeared on it's own within 1.5 years. If the cyst hadn't been seen on US, we would never have known it was there. She was completely unphased by it. I give God all the glory for that one. That's a huge cyst, esp. on a tiny baby. 10 weeks ago I had our 6th baby, a 10.2 lb baby boy. Blessings to you, mama. Please continue to post about your delivery & baby.
