Check a PG test: Assuming that is negative, many pills do not build up enough tissue in the endometrium to cause a period and the way to show that is a pelvic ultrasound that I do in my patients to prove there are no problems. If that is normal you can either continue with the pills, as you do not have to have a period on the pills( many women like that) or switch to a higher dose pill to get periods.
