Thanks everyone for your support, its really helped me.

If for some reason I decided to have an amnio (which I'm not going to, I don't feel right about it) and got told that the baby won't survive or has little chance of survival I would still carry bubs as long as my body allowed.
My nana overseas told me a story where a member of her church was carrying a baby and it was diagnosed with having its brain develop outside her skull. They were told to terminate but it went against everything they believe in. Their little girl only survived a few hours after being born but they said that they wouldn't have given up those few hours for anything.
My auntie has brittle bone disease. When she was pregnant with my cousin she was told to terminate because little katrina had broken her femur in the womb. She was told a few times to terminate. Katrina is now a normal 7 year old. Yes, she's broken a few bones, but she's completely normal.

I've researched Oligohydramnios (low amniotic fluid) and nowhere have I read about having an amnio. One of the only things that can be done to correct this problem is giving mum lots of fluid. So, I've made sure that I'm drinking plenty (I'm usually hopeless at drinking!) and I'll see if that improves anything.

It's just so frustrating!

Thanks again!
