Hospital isn't doing their job and I'm kind of pissed

So it may not seem like a big deal but after I got my weight logged today the doctor told me to be careful because I apparently gained 9 pounds in two weeks since my last appointment. I told her that can't be true because I was 152 at my last appt and was 154 today. After saying I was 152lbs at my last appointment she said then I wouldv'e also gained 9 pounds since the appt before that. No. Like how can't you people do your job?! It's so simple. I have a whole weight log since the beginning of my pregnancy and I'm doing a better job than them. I would rather start going somewhere else for my last 7 weeks because this is just stupid.
