What to expect at 16 week midwife appointment?

Is it worth going to as its out of the way and I've heard a few people saying it's a waste of time apparently they just take a pee test ?? And secondly whenever I do try contact my midwife she ignores my messages and I found her useless for when my sister had her aswell Almost 2 years ago 
And my first appointment was exactly the same but they did paper work then took my weight and blood pressure
