I have been charting using the sympto-thermal method for about 4 months now- I think I am on chart number 5 currently and I am getting married in a couple of months. At first, everything seemed really normal and consistent, but now my temperatures seem all over the place and I am getting really confused about what is going on.
My first few cycles always followed the same temp pattern- I would be in the upper 97 range for most of phase 1, then go lower when phase 2 was beginning, then dip really low (below 97) before ovulation and start coming up again slightly. Then, around days 17-19, I had a very clear thermal shift and my HTL was always quite a bit higher than my LTL, so I could clearly tell when phase 3 began. My mucus patterns were perfectly in line with all of this.
All of a sudden, for the past two cycles, my temperature barely drops during phase 2, so it is in the mid 97 range and then the "thermal shift" might be .2 or .3 degrees higher. I can still tell, based on my mucus, where I should be cycle wise, but I am really confused. Has this happened to anyone else, and do you have any ideas why my thermal shift seems to be non-existent now?
Thank you!
