Aiyo, sakit sangat kan time ni! At 35 weeks, your uterus dah besar, so memang coughing puts pressure on your belly and ligaments, normal la, but if it's really painful or you're worried, better check with your doctor just to be safe. A few of my mum friends said drinking warm water, honey, and ginger helped ease their cough during late pregnancy, so maybe try that jugak while waiting for your appointment.
