I took provera and finished my last couple of pills of Clomid yesterday. According to the <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> my most fertile day is December 12th. This is based on the period that was brought on by Provera. I did buy an ovulation kit and will start testing on day 12 which is the 10th of December. How accurate is this <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a>?
