Can you tell if a cycle was an anovulatory one?

If you have pcos or any other hormone imbalance you can sometimes have more LH hormone in your system to trigger the test but not ovulation. My doctor said a temp chart is the most accurate. Progesterone causes your body to get a rise in temp AFTER ovulation. If ovulation does not occur LH increase or not, you will not get a temp rise.

Hope this helps. Also keep in mind the temp chart confirms ovulation but is bad at predicting it because the temp rise occurs a couple of days after ovulation but gives you an idea of how to time next month and when to start with OPK tests. There is also a microscope called fertile focus. I was not sure if it would work but it worked for me and all three agreed on when my fertile peroid was.

Hope this helps.

If you are not charting basal body temperature (the only sure way to confirm ovulation actually happened, OPKs don't guarantee that) you can only guess by the length of your cycle. After about 35-45 days, the longer the cycle gets, the more likely it was anovulatory.

No.. none of us would have a clue. Even if we all used opk's monthly there would be cycles you don't see a positive.

Happens all the time apparently, I was diagnosed years ago with unexplained infertility and was told it can happen 1 in every 10 cycles in the majority of women.

Without a test you can't know for certain. Unless you have been diagnosed with a fertility problem you should be ovulating every cycle.
