Dizzy?!

Danielle • 33yo, first time mom and so excited for it all!! Married 10.03.2014 and we are over the moon about our Nov baby boy!
I started getting serious mornin sickness as of two days ago... This morning I woke up to shower and get ready for work and got so incredibly dizzy I had to lay back down for fear of fainting.
No other symptoms other than the normal ones... 
Has anyone else experienced this???
