I’m 11w4d and today while showering I got a dizzy spell I had to open the curtain and bend down on the tub. I got out and laid in bed. I drink a bottle of water also. Is this normal at this point? I thought you don’t get this til second trimester? I could also be further along than I think I haven’t been scheduled and ultrasound yet and currently switching doctors.. idk if I have low iron but is it necessary to just start taking prenatals with iron in them anyway?
