Anyone here experience one off ovulation per year, every year same month your body decides to go on vacation and not ovulate.

For last 3 years, ever since I met my husband, every dec I don't ovulate. Rest of the year it's like clockwork. 2 months ago I stated BBT & OPK. Surely enough dec my Temp just could not stay up even though I had all the other signs like EW mucus and positive OPK.

For those who experience this, what do u do. Do you continue tracking temp or just give up & start over after ur next period
