I have one of these in August to, no idea what it’s about. I wish the letter gave more info xx
I have one on Friday and had one few weeks ago too. They just check heartbeat, check urine/bp and discuss the reason behind why you were referred to obstetrics as usually you wouldn’t be I don’t think
From my experience they usually check your urine, blood pressure and listen to baby's heartbeat. If you can't eat prior to the appointment they would let you know beforehand this has never been the case for me.
