I've got this rash on my body, gets itchy when I'm hot and then I keep having blury vision, like double vision and feeling faint. I've been the doctors and he said my blood pressure is okay and my temperature is fine. But he's signed me off work for a week which I don't understand? He says I need to see him Thursday morning to check me over again. Has anyone had this in pregnancy and should I be worried? I'm 18 + 3 weeks pregnant.
