Hi, this is my first pregnancy. I'm 39 and due in 3rd April. Due to having a genetic condition I was sent for extra scans at 30 and 36 weeks to monitor babys growth - which is fine - if anything she is big! My concern is that I've been told I have Polyhydramnios, which is in the mild range. However I am still worried. I'm going to have a fasting blood test tomorrow to check for gestational diabetes, but it seems unlikely that this is the cause. Has anyone else had polyhydramnios? Hearing other peoples experiences would be really helpful! Sarah
