Ob-Gyn questions? Ask a gynecologist online.
Hello, I'm Dr Manos, board certified obgyn. Anytime you saturate two pads an hour that is considered too much. A tampon and pad every two hours would raise concern if you are soaking through. Is this your expected period? Have you been regular up to now? Are you cramping much?
Light and occasional delayed periods can indicate not ovulating regularly. You definitely need the scan to include measuring the thickness of the endometrial lining of the uterus.
