Amniotic fluid

Zorayah • I'm a FTM engaged due Jan 8th,2016 with a little girl 💜❤️💗👶🏼
I'm 35w&4d I go to the ob once a week and the hospital for NST (non stress testing) twice a week due to crazy blood pressure it will be really high then drop etc. well today was my first day for NST and my blood pressure was fine but my little girl wouldn't stay still enough for a good reading so they woke her up with a vibration thing and then she wouldn't calm down her heart was everywhere as well so they got concerned and gave me an ultrasound to make sure everything is okay with her and they said it is they wouldn't say a weight geuss but the nurse was concerned about our high amount of fluid the cut off was 7.9 or 6.9 and I had it at 6.7 or 7.6 either way that's why they have issues getting her heart rate and what not so my question is what is to much? What do they do if you have to much? Have any of you had these issues?
