Lightheadedness

Hey ladies, I'm 5 weeks today with baby #2 and boy am I feeling lightheaded! With my first pregnancy, I didn't have any morning sickness, lightheadedness, or bloating. This pregnancy seems to be different as I'm lightheaded and bloated. Also, I feel full all of the time and have been 'forcing' myself to eat. Any suggestions on how to get through this?
