Pregnancy test: If you have had unprotected sexual intercourse and/or are using a reliable form of birth control then you could be pregnant. If you think there is a chance that you may be pregnant, you should do a home pregnancy test. If it is negative. If you have had unprotected sex, you should also be checked for sexually transmitted infections which often cause menstrual irregularity.
