I’m 33w3d and I ate a little bit, and laid down for a little bit and then while I was laying down I started to get really lightheaded, I really thought I was going to faint. it got super hot and it got really bright in the room and there were like black spots in my vision. I called my mom and she told me to lay with a pillow under my feet so my feet were above my heart. I feel better now, a little dizzy still. I have no idea what happened but now I’m worried it could’ve been something wrong with the baby. I have always had good blood pressure, and my only problem is that I have a pretty fast heart rate (usually 115-125) but my doctor never says anything about it. should i go to the hospital?
