I'm lightheaded all the time - have been my whole pregnancy but it's getting worse. The severity comes in wave throughout the day. Even when i'm lying down i'm lightheaded. My BP is fine(i have a machine at home). I have a midwife appt tomorrow but thought i would ask if anyone had something similar. It's getting debilitating. I don't want to drive just in case i faint, i hardly go out. I've already spent the majority of my pregnancy in bed because of HG. i really am just over being in bed. I want to be up and about like normal people. i can't even play with my kids. Doing anything is exhausting and my head feels bad all the time.
