I’m looking for help determining the beginning of Phase III in my current cycle. I’ve read “The Art of Natural Family Planning” and have been charting my cycles since August. I got married in November. My first 3 cycles were 31-34 days and my mucus and temperature were fairly easy to track and interpret. I usually ovulated around day 18-20. Since then, I have had more trouble reading my CM, and the pattern isn’t always clear.
The following cycle, however, lasted 47 days (probably because I was stressed before my wedding). Thankfully, I entered Phase III a few days before our wedding!
I began my current cycle on November 17 (so it has lasted 45 days so far!!). I had very fertile mucus on days 16-20, but no temperature rise after that. So, I concluded I did not ovulate. I continued to have little mucus for the next several days. I had breakthrough bleeding on days 34-36. My temperatures ranged from 97.2-98.0 for the first 38 days of the cycle. But there were no 3 temperatures in a row that were higher than the six before them. However, I think I had a strong thermal shift last Thursday through Sat. Here are my temps from days 34 - 46
day 30 (Dec 16) - 97.6
day 31 (Dec 17) - 98.0
day 32 (Dec 18) - 97.9
day 33 (Dec 19) - I took it, but forgot to record it
day 34 (Dec 20) - 97.7
day 35 (Dec 21) - 97.8
day 36 (Dec 22) - 97.6
day 37 (Dec 23) - 97.7
day 38 (Dec 24) - I took it, but forgot to record it
day 39 (Dec 25) - 98.0
day 40 (Dec 26) - 97.9
day 41 (Dec 27) - 98.0
day 42 (Dec 28) - 98.2
day 43 (Dec 29) - 98.2
day 44 (Dec 30) - 98.1
day 45 (Dec 31) - 98.0
So, I think I have an overall temperature shift beginning on Day 39. But I drew my LTL at 97.8 (considering days 19-24–which includes 2 days I didn’t record my temp; unfortunately, my temp was at 97.9 and 98.0 the two days before that–do I need to use those temperatures?). I drew my HTL at 98.0. I think I have a strong thermal shift from days 41-43. Then the last two mornings went down 1/10 a degree.
I didn’t notice any mucus the past several days; except for a little bit of very tacky, white CM yesterday.
Can I go by temperature only and say I’ve entered Phase III?
My husband and I would really like to have sex tonight on New Year’s Eve. Do I need to wait for tomorrow’s temperature–if so, how high does it need to be?
Is it possible I ovulated back around day 20, when I had fertile mucus, but DIDN’T have a temperature rise and my breakthrough bleeding on day 34 was my period? (I usually have PMS and I didn’t then.) I like to rely on temperatures more because it seems to be a clearer sign for me.
I don’t have anyone I can ask about this; I haven’t gone through a class.
