What happens here

Hi all you gorgeous mommies!

So I am currently 14 weeks pregnant and I got a letter from my hospital for my Ante-natal clinic appointment. ( I will be 16 weeks then)

This is my first pregnancy and can anyone tell me what to expect? On the letter it says that it can take between 60 -90 minutes and I have to go alone without my husband, to ensure my privacy.

I am absolutely terrified as I don't know what to expect or what will happen.

The letter didn't state anything.

Any help please, I am a nervous person XD
