Symptoms
By Mayo Clinic staffThe main symptom of infertility is the inability of a couple to get pregnant. An abnormal menstrual cycle that's too long (35 days or more) or too short (less than 21 days) can be a sign of female infertility. There may be no other outward signs or symptoms.
When to see a doctor
If you're in your early 30s or younger, most doctors recommend trying to get pregnant for at least a year before having any testing or treatment.
If you're age 35 to 40, discuss your concerns with your doctor after six months of trying.
If you're over 40 or have a history of irregular or painful periods, pelvic inflammatory disease (PID), repeated miscarriages, prior cancer treatment or endometriosis, your doctor may want to begin testing or treatment right away.
