have had all three for two nights now, I am also feeling floaty headed. I called NHS direct and they suggested I go to the hospital but I lent the car to my dad and I cant ask him to come and get me now he is in his 60's and has work in the morning :( I am worried to try and go to sleep as when I try to relax I start gasping again. Has anyone had this before ? I am not sure what to do. (10 weeks with 3rd baby)
