i was with Dr YC Goh previously @ Thomson Plaza.
i usually pay $100-$180 for each visit including scan & supplements.
after sometime we were offered to sign a package at around $700 whereby we do not have to pay for consultation & scan anymore till you deliver. things chargeable still are medication, supplements, extra tests etc.
as i went thru c-section, the operation fees was $2000 excluding other charges.
