Coughing badly belly cramps at every cough at 37weeks

I've been having sore throat for the week and this past few days I start coughing it got worse and everytime i cough my tummy cramps up, very bad abdominal pain. First it was the right side then the left now the top side . I've tried home treatment drinks like honey, Yuzu and lemon honey, three leg cooling drinks. It doesn't help. What to do..... horribly painful to even sleep due to the cough and cramps I have appointment with my gyne later today But am i even allow in NUH clinics if im coughing ? .. crying out loud*** #advicepls
