Anyone experience hyperemesis gravidarum?

Kellie
I'm almost 12 weeks on Thursday and I've had "morning sickness" since I was 5 weeks and I've lost 7lbs and can't hardly keep food down or water at all. I don't urinate a lot hardly at all anymore. And I puke bio almost every day. I've been to the er twice to get fluid now. How could I ask my Obgyn about this? She's never even brought this up.
