I am glad your doctor says it is okay and normal for you but for anyone else out there who might experience this, I think they should treat it as if it is not normal because if you are leaking that means that there is access to the baby from the outside world and if there is access to the baby from the outside, the risk of infection is very high. Most women in this situation are admitted to the hospital and given an IV to help ensure the amniotic fluid is sufficient for baby.
It's good to hear that the Dr thinks everything is alright. It's a little weird though, I didn't know you could leak amino fluid and that was normal... I guess you learn something new everyday, lol. Good luck on your u/s it's fun to see the baby's. I go for my 3rd stage 2 u/s on wed to make sure my little girl is still growing right! Again, I'm glad everything is ok!
