I am 16wks now. I would say... if you don't have complication you can go to private gynae.
Maybe SGH has shorter Q time. NUH is pretty crazy this round. not sure y it become so popular after 2 yrs from my last delivery. hahhaa. I was very pleased with the services provided by them during my last delivery, i might switch to private at my last tri if I meet a good doc and my condition is stablised.

My issue is the long term mediciation cost which is a preventative measure for sustaining my pregnancy. $7.50/jab/day vs $2.8/jab/day, the choice is very obvious for me.

If not i would have gone to a private gynae. hahaha
Not sure about SGH but NUH don't scan your bb on every visit. In fact, i seen the doc 3 times and i was only being scan once for Oscar test, the rest of the time is just listen to heartbeat.
