I am 28 weeks pregnant and I am feeling really weird. I feel like I have motion sickness along with an out of body feeling and like I have lost blood.

Weird feeling. Anemia would be the most likely explanation for your symptoms. You should be scheduled for your gestational diabetic and anemia screening typically around 28 weeks.
Get a thorough exam. If your OB says your CBC is normal, ask about low blood pressure. Eat 6 equal meals spread out, stay well hydrated, avoid processed food and sugar, eat healthy foods, get 8 hours sleep, move through the day, and lower stress. This may be a wake up call to improve health. See kelly mcgonigal 's book the will power instinct for helpful hints about making changes.
