The gynae I visited for my first pregnancy increase their price by a huge margin and we want to be prudent with the second pregnancy. Do you think I should visit the same gynae as they have my medical record (diabetes & Thalassamia) or I should change?

Since your priority is to cut costs, then there's not much point sticking to the same gynae. I was a fully subsidised patient and experienced a very smooth pregnancy and delivery with professional staff. Medical records in Singapore are linked but that only applies to public health care institutions. Therefore, you may want to request for a copy of your medical history. In my opinion, there is quality care even at a public hospital. http://yourhealth.asiaone.com/content/1-patient-database-serve-all-public-health-care-institutions
