My wife is depressed and said she does not want the baby

Hi..I have been married to my wife for almost 11 years. We had actually given up on having a baby. Thought there may have been something wrong with one or both of us. My wife and I accepted this as sign that maybe we should not have children. But a week ago, after three pregnancy tests, it happened. We went to the doctor to confirm with a blood test. She is 3 to 4 weeks pregnant. My wife has high blood pressure and therefore is a high risk pregnancy. We both went to her doctor again the next day to have her blood pressure medicine changed; he also got her an appointment with an OBGYN. Its the usually worries about money and what to do next. I thought she was happy about the pregnancy, but she is not. We were even going through a name book to pick a name we both liked. Last night she told me she did not want the baby and things between us will never be the same. I know pregnancy can cause hormonal shifts. Unpleasant or even hurtful things can be said. She says she does not want to go on with the pregnancy. She is sure that i do not want the baby either. I worry about money and change just like her. I love her a great deal and do not want to lose her over this. I keep telling her that we can make this work, it may not be easy but what in life is. Today i told her we need to talk this out. She told me it was not my decision anymore. Neither of us really believe in abortion, so her wanting to terminate is out of the blue. I would love our child if we have one, but it would not be the end of the world if we do not. I just want her to be happy with our choice whatever it is. Please, someone help.
