Lack of menstruation is possible positive sign of pregnancy; It seems that the other symptoms you’ve mentioned are not (wet and leaky in vaginal area with milky discharge, tightness, and cramps). All of the latter symptoms are present in many other conditions. Lack of menstruation should be treated as the first and potentially serious sign of pregnancy, although lack of menstruation does not always mean pregnancy. That’s why a missed period should be checked first with a home pregnancy test and then confirmed with a blood test and ultrasound.
