Family trouble

Is anyone else finding their family taking advantage of you while your pregnant. My brothers/sisters in law all want to go out drinking whenever we get together which is not so fun for pregnant people. Also they always try to get drunk and make me drive.

I am currently working full time trying to keep my vacation days for doctor appointments and after the baby and they keep planning events when I work. When I ask if we can push them back until later in the day they get mad that I'm messing up their schedule.

I get it that I'm tired and not so fun and that if I can't join in that's not their fault. But really can't people be a little more sensitive especially family!!!!???!!!!
