Has anyone ever had dizzy or faint spells???? I think I'm between turning 3 weeks pregnant. When the app calculated it said 4 weeks but I am at my very earliest stage !  I was just at Best Buy now and all of a sudden I had no control over my body all I new is I felt like I was going to just calapse to the floor and if my husbands arms weren't in a reachable place I would've been on the floor. Worst feeling ever ! And yet scary ! Help because I'm not sure !
