Ultrasound appt postponed again!!

Supposed to go for the appt at noon but when I called them, they felt that I'm still not well enough as they heard me coughing.. They do not want to take the risk of me coughing while the needle's poked in :(
Sigh! (yippee!) So appt will be postponed again. However, I was advised to see the ENT doc one more time to see if there's anything else we can do should my cough persists..
