My temperatures don’t seem to show a sustained rise and the online charting system hasn’t detected ovulation.
Occasionally a chart may look anovular (without ovulation) even though ovulation has occurred. If your temperatures are particularly erratic or you don’t have enough reliable information recorded on your chart, it may be impossible to identify ovulation. Consistent recording of fertility signs is crucial for accurate chart interpretation.
A very small percentage of women do not show a clear temperature rise after ovulation. If your cycles are regular, and you consistently experience a patch of fertile cervical fluid 10 – 16 days before your next period, you may in fact be ovulating despite the absence of a bi-phasic chart. A progesterone blood test 7 days after your fertile fluid disappears will help establish if you are ovulating.
Alternatively, you may indeed have experienced an anovular cycle. A cycle without ovulation could turn out to be a one-off instance or a common occurrence. Anovular cycles will definitely affect your ability to become pregnant, because without an egg, fertilisation and pregnancy cannot occur.
For information on possible causes of anovulation and what you can do about it, please check out the resource ‘Your Guide to – Anovulation’ from Step 3 of the Program.
