Coughing badly

Hey mummies. I’m currently 20+ weeks and coughing for one week. The cough got worse, tried GP medication doesn’t work. Been coughing super badly until I visit the toilet a few times in an hour. During night time can’t sleep and visit the toilet as whenever I cough urine keep leaking. I’m a bit worry about my baby. Called KK they say more than 22 weeks need to go to delivery suite there. Is there anything to worry about and should I go to the delivery suite to see the doctor there? But the thing is I’m not a KK patient and my gynae is currently overseas.
