This research uses Certainty Factor , parallel Certainty Factor method and forward chaining inference tracing method. The aim of this research is to help a pregnant mother diagnose any disease during pregnancy without the need to meet an expert. The data includes symptom, disease/illness, and solution in its working. System testing shows that the system is able to diagnose the disease while pregnancy based on symptoms suffered by the user. This research involves 12 respondents, consisting of a diverse and widely variant group of people, in order to do the trial system. For the interface and access system, the results are 56,7% strongly agree, 40% agree, and 3,3% neutral. Meanwhile for the functional system, 99% users say that the system has run well. When tested with two people consisting of the knowledge engineers and the experts, 90% are strongly agree, and 10% are agree for the interface and access system, while for the functional system, they are 100% user agree that the system works well but the remaining 1% are not. The accuracy for the diagnostic system and doctor’s diagnosis test results is 76,7%
