You're a doctor and a surgeon, so you'll be making some serious bank. It's a stressful job, but being the conductor of the maternity orchestra is hugely rewarding. A plain old general practice doctor makes about $175k. Taking care of women and their pregnancies is good business and you could be bringing in about $250k a year.
You will make about $40k more if you are a man (not that you can do much about it). You'll get much more if you work at a hospital and a lot less in private practice. You'll be paid the least if you work at a college or university.
