I'm a pregnant medical resident, what do I do?

I just found out that I am pregnant and this is my second year in residency and have 2 more years to go. I have a feeling this could possibly ruin my medical career. My parents don't know and I don't want them to know. I am currently 27 and I know it's a perfectly good age to have a baby but my parents are extremely strict and old fashioned. They always say that girls have to stay a virgin until your married and then have a baby and if your not your considered "worthless" to a man. Plus my parents do not like me having a "white" boyfriend and prefer me to have Asian one, because they are more "secure". My boyfriend is happy that I am and he'll try to take care of the baby since he this is his last year being a resident and the hours aren't as demanding. We've been together got about a year in a half my mother says whatever and my father does not like it. I don't want to end up like my sister because she was in a similar situation but was fortunate not getting pregnant, after 5 years he left her and now my parents look down upon her. I don't want them to be ashamed of me and I do not believe in abortion. What should I do?
