Up to 50 out of 100 women and men infected with trichomoniasis (trich) do not have symptoms.2 If symptoms develop, they usually appear within 1 week after a person is infected. But symptoms can develop months later.
Symptoms may be worse during pregnancy or right before or after a menstrual period. Symptoms in women may include:
Large amounts of pale yellow or gray-green, sometimes foamy discharge from the vagina.
