Hi mommy. Painless means magpapainject ka epidural which is tinuturok sa spine sa likod. Gising ka pero walang pain during delivery. Natural, unmedicated birth means otherwise - no medications at all. In some studies, it has been found na mas higher ang chances na ma CS if may medical intervention like induction and using epidural as well. In my own experience - CS ako sa first pregnancy (i was induced and nag epidural din). Second pregnancy ko was VBAC - natural unmedicated delivery and it’s worth it. :)
