If her period is late, she could be pregnant but it has to be confirmed with a pregnancy test. Lack of a menstrual period is the first, albeit insecure, sign of early pregnancy. The other symptoms such as nausea and vomiting in the morning, cramps and fatigue are even less reliabel signs of pregnancy. Your partner can take a home pregnancy test now. If the test is positive, she can go to a gynecologist for an ultrasound check of the fetus.
