You're welcome!

I completely understand the long wait in the public hospital but you could visit Dr. Wong or other private doctors in the meantime.
Dr. Wong charges 800/1100 for consultation and 600 for ultrasound. I've ever only been charged 1100 for consultation but every time I see him I am there in either his ultrasound & consultation room for at least 30 mins. I do have to wait about an hour to get called though but if you are able to get the earliest slot (10:30), it's the best one. For my first trimester, I've seen him more often than normal because I am paranoid haha! I had an mc last year and Dr. Wong also wanted to ensure that this time I am taken care of from the very beginning. I saw him on 4w2d, 7w2d, 8w6d, 10w5d and 15w6d. I was supposedly only going to see him about every 3-4 weeks but there was a time when all my symptoms vanished and was so scared so I saw him the week after.
He has been very supporting of the public + private route I am taking and have suggested that the visits I have between him and the public hospital be at least 2 weeks apart.
As for the public hospital (Pamela Youde), after registering with them at 5weeks, my first appointment was in:
-9w1d for blood tests
-12w2d for my down syndrome test (ultrasound and blood test)
-14w5d for the antenatal check up (first time in seeing an OB in the public hospital and she discussed my results with me, says it was normal. A doppler to hear the baby's heartbeat, check my breasts and did a papsmear.)
-21w3d for the anomaly scan this Wednesday. I did have a thread here on geobaby asking about this and turns out not all public hospitals offer this as they may have limited slots.
Sorry for the long post! Hope this was helpful!
