6 weeks - no vomiting, but severe dizziness

Hi, I just found out I'm pregnant (I found out a week after my missed period, also when I started feeling nauseated around people eating)... I'm 5 years post-op, but curious if morning sickness is worse for post-opers? I've never felt so dizzy, and i have never in my life had any kind of motion sickness... it gets so bad some days, that I can't even look up without feeling like my head is spinning... I almost fainted the other day.... I've always been good about keeping my fluids up, but I'm on vacation right now, so I kinda feel stranded as far as support about this... anyone having similar problems and is it normal? I almost wish I could just puke when I feel this way, but even right after eating, I can't actually throw up... just feel nauseated and severely dizzy some days... :(
This is my first pregnancy btw...

Very normal. tha'ts actually a form of morning sickness, extreme dizziness.  i had that with both babies.  but i would get your iron levels checked when you get back, you could also be anemic.
