Hypermesis gravidarum?

Ok so first off, I'm 12w 6d.  I haven't been able to see the doctor yet so that might be off.  I don't have my first appointment scheduled for another two weeks because the one and only Obgyn in my town is super busy.  
My symptoms are basically these:
1.  So much nausea and vomiting!!  Seriously, in the last couple of weeks there have been several days(around 5) where after around noon I can no longer keep anything down. It's not uncommon for me to throw up five times a day.  Yesterday I'm certain I hit double digits.  Anything I put in lasted about 45-60 minutes before I threw up.  Ginger doesn't help.  Peppermint does a little, but mostly as relief afterwards instead of prevention.
2.  I get dizzy really easy.  Several times a day I get dizzy when I stand. Bsometimesbi have to hold myself up and breathe deeply for a few seconds before I can walk.
3.  Headaches.  Not super bad, but a lot more common than usual.
4.  Peeing?  So I have never been the type of person who peed a lot.  Pre pregnancy I would pee twice a day.  Now it's more, but still only like 4 or 5 times a day.  I don't know if that's normal for pregnant women.
Thoughts?  From stuff I've googled I'm afraid I have HG.  What do I do about that?  I don't know if I can get in to see my OBGYN anytime soon and I don't want to waste my time if all I need is a nap and some Benadryl.
