Anovulatory cycles, cycles without ovulation, is generally nothing to worry about, as it’s quite common that they occur sometime during a woman’s fertile years.
This is especially common for you who have recently used hormonal contraception, as these most likely have worked to inhibit ovulation during your use of them. It may take up to one year before your body’s cycle is back to regular, during which time anovulatory and/or irregular cycles are common.
Other factors are:
Extreme change in diet and/or exercise
Medical conditions (i.e. PCOS)
The bleeding that follows an anovulatory cycle is caused by the estrogen rising again rather than the progesterone decreasing and may differ from the normal menstruation in length and abundance. The cycle will likely be longer than usual, and your temperature will remain low during the entire cycle.
If you suspect that this, or a previous, cycle is anovulatory we recommend you to check your graph and compare to previous cycles in regard to length, ovulation day and temperatures. If your temperature remains low, under your cover line, ovulation has not occurred.
When you’re not following your fertility, an anovulatory cycle is very rarely discovered, perhaps you’ve noticed that your period is a bit late but didn’t put much thought into it.
