So lately I've been feeling extremely dizzy when I get up from my bed or couch or chair and feel super lightheaded , I feel so light headed it's bringing the nausea back that it's making me throw up again ( I don't miss throwing up ) or as I lay in bed I feel like I'm on a boat an I'm rocking back in fourth with the ocean it's so weird almost as if I'm buzzed An the room is slightly spinning ... I've read this is normal an not yo worry unless I actually pass out which I haven't , I've been drinking lots of water through the whole pregnancy what can be causing the dizzy spells ? My hormones? Pregnancy all together? Not enough of something I need during my day ? I'm 25 weeks and 3 days , please help
