Just sharing my own experience, private gynae at TMC, no package. Pay per visit.
Each visit consultation $100, scan $80. Exclude supplements ($50-$60 a month). From 2nd trimester usually 1 visit a month. Last 2 months will shorten to 3 weeks then 2 weeks then weekly. Some gynaes offer package to cover 2nd trimester and 3rd trimester. Set aside 3k to cover the costs.
Tests
1st trimester scan + 20 weeks scan - $450
NIPT tests: Oscars around $400+, if opt for harmony or panorama $1200.
Some other routine blood tests are also needed. Add a few hundreds.
Hospital bills
My hospital bill including bed and ward, delivery suite, epidural, gynae fee, anesthesiologist fee, PD fee came up to $11k+ for single bed, natural delivery.
Need to factor in $1k additional if planned C-sect. And even more if emergency C-sect.
