How to prevent pregnancy when blocking antibody is negative

If the blocking antibody is negative, this situation is pregnant, and it is really easy to cause abortion. It is necessary to use some immunotherapy methods under the guidance of doctors, such as immunoglobulin, progesterone and vitamin e for fetal protection treatment. This situation must be persisted until three months later. After the fetal development is stable, the drug can be stopped. After three months, the probability of abortion will be reduced a lot. Therefore, these three months are the more critical time for fetal protection. In addition to medication, be sure to stay in bed and not do strenuous exercise.
