The current health care system provides you with many options. You may choose to have an OB- Gyn, midwife or a general practitioner as your care giver during pregnancy and birth. Depending on any issues that arise during pregnancy, you may need the services of a specialist. In addition blood tests and ultrasounds may be ordered to ensure that all is well with your pregnancy.
Make sure you have medical coverage or else it can get very expensive for your pocket.
