Infertility/Fertility/what's happening with this chart?
I have been charting my bbt with fertility friend for 8 cycles, so I have gotten very familiar with my system. This month I had a clear and obvious thermal shift on cd12 from 97.6 to 98.3. My temp stayed up for 8 days (above 97.9)then began to slowly fall so I expected my period to arrive. After 3 days of lower temps, fertility friend removed my cross hairs and now says I did not ovulate. After 5 days of lower temps, again my temp has shot back up for 2 days. My usual cycle length is 24 days and now I am on cd27. I have had anovulatory cycles before but they never showed a clear thermal shift (esp for 8 days), like this one does. Also, I did have spotting on the days of lower temps when I thought my period was coming. I never spot so this was odd for me, and it was only when I wiped, never enough for even a panty liner. In your professional opinion, would you say this was an annovulatory cycle and should we treat it as such or would you reccommend I test? I have never had a cycle like this before. Any advice you can offer would be so appreciated. Here is my chart.
Hello Jeniene from the U.S. (California),
Of course there is no way for me to know exactly what your physiology is doing based on a temperature chart, but I can probably offer a possible explanation. Temperature charts are NOT really measures of ovulation, rather it is a measure of the progesterone rise that should occur from the point of ovulation. The progesterone hormone is thermogenic and so there is a slight rise in temperature. The fluctuations you are seeing may be fluctuations in this hormone which is a sign of a hormonal imbalance such as would be seen in anovulatory cycles. So, I agree that this chart may indicate that this is an anovulatory cycle. In order to get pregnant with anovulatory cycles, ovulation ("fertility") medication is used to induce the ovary to function correctly.
