Previously, while on Femara I noticed the same thing happening. Our first cycle was optimal. We have great P4 levels, ovulation occurred between CD15-17. Then the next cycle my ovulation came a little later and my P4 was lower. The first time doing Femara I saw a line change on CD15 and by the second and third round I was not really seeing a significant change on the OPK and ovulation got further and further apart. Making detection hard so we moved to a more monitored cycle using injections. I think we need to use Femara and monitor it next time; if there is a next time.
I hate this shit.
UPDATE: This is the email I got from my nurse...
Good morning Teresa,
So in looking at the OPK’s I am inclined to think that cycle day 16 is positive. You may have ovulated yesterday which would account for your elevated temp today. I don’t know what to think about the smiley face digital, we don’t typically use those. Lets’ check a progesterone level on March 5th, in one week, to see if ovulation has occurred. I will send lab a lab order to St. Charles today. I recommend having intercourse again today.
