Okay, so I've been pretty much fine since I got pregnant, but yesterday, at 11w+6d I would get dizzy for like 3 seconds every time I bent over and stood back up (which I've been doing a lot of, because we are remodeling our house-- and yes, I'm using a respirator mask so I'm not inhaling dust/fumes). Since I woke up this morning, I have felt pretty weak and dizzy.. especially when I bend over and stand back up. I don't know if this is related, but from about week 4-week 6 I was taking prenatal samples. I kept forgetting to get my OB to fill my prescription (I know, I know) but I finally got them filled at 11w+3d, so I've been taking them every day since then.. could the prenatals be related? Even if not, has anyone had any experience with this?
