Glucose test

C💙

I have questions so I was told mine was high and I have to take the 3 hour test.. I’m seriously sad about this the drink made me feel horrible this is my 5th kid and never had this problem..I’ve ate the same with my pregnancy if anything less in this one I can’t finish a whole meal what causes this ? Is it something I’ve done ? This pregnancy is the most ive Gained and due in May I’m having the worst time excepting my weight at the moment.. is there a chance I won’t have it? Or is it most likely u do if u failed the first?
