KKh subsidized route: Scans

Hello, I'm under kkh subsidized route and aware that I cannot choose my doctor etc. My upcoming checkup is arranged only with doctor then subsequent 1 mth later, then detailed scan. However I have been having bleeding here and there for days on and off last 2 weeks... can I request to top up for a scan? Anyone has made such request previously? #advicepls #firstbaby #firsttimemom #pleasehelp
