"Came out of the appointment nervous and totally uninformed"

As a first-time mum, every appointment I get nervous and hope the doctors can explain everything I need to know. Unfortunately, this hasn't been the case. My husband and I recently went for our 31-week scan. We came out of the appointment very nervous and feeling totally uninformed. The doctor hadn't explained anything. When my husband asked questions (1st time dad), they mumbled answers so we couldn't understand or hear them. All we gathered from the appointment was that i have too much fluid around the baby and that I would need to do another diabetes test. The first 1 came back negative week 27. They didn't say if the heartbeat was good or if the baby is ok. I left the car park very upset and anxious.
