Yeah I had one when I was pregnant it was just answering questions and they tell you what pain relief they are happy for you to have during labour.
I had one the other week, I asked why I had to go and it was because I have a blood disorder so they needed to make sure they were aware of the ins and outs of my condition for pain relief purposes. To be fair I have to have a section so it was worth it . Do you have a medical condition? As that could be the reason you are required to attend x
I have one booked for September due to being born with a mild form of spina bifida. I'm assuming it's to see if I'd be allowed an epidural if it's needed. X
Maybe that's the reason? If they are anything like the anaesthetic dr I saw they will explain why you are there x
