Testing the woman first looks at whether she is ovulating each month. This can be done by having her chart changes in her morning body temperature, by using an FDA-approved home ovulation test kit (which she can buy at a drug store). Ovulation also can be checked in her doctor’s office with an ultrasound test of the ovaries or simple blood tests that check hormone levels, like the follicle-stimulating hormone (FSH) test. FSH is produced by the pituitary gland.
