I see my OB again this Friday, but last Friday I attempted to take the gestational diabetes test and about half hour through, it didn't stay in my system I got the sweats and my vision went all blurry and I almost passed out, now today I had a bowl of cereal and added like a little spoonful of extra sugar info and again about an hour after I started to feel sick and got alittle dizzy, anyone know what this could be? Or how I could stop it? I'm 27 weeks pregnant
