Certain I O'd on cd 16, FF says cd 15???????

Help! I was temping, opk'ing, etc. like crazy before my IUI this month-had two this week, back to back on CD 15 and CD16, and I was sure that I ovulated on CD 16, which would have been perfect, because my temp rose to 98.1, and I usually ovulate the day before I get a temp in the 98's....I was shocked to see it give me CD 15 as my O day. I got my peak on my clearblue monitor morning of cd 15, then + opk's cd 15 and 16 (actually darker on cd 16), and had the most EWCM on cd 16, too. 

 

Could someone take a look at my chart? I think I did get up once the night before the CD 15 temp, but still...it doesn't seem like enough of a rise above a coverline...isn't it weird that FF detected that as the rise and not the next day's temp??  Shoot!  I was absolutely poitive I O'd on cd 16...I always do...

I don't always agree with FF's assessment of O day.  However, your chart is still uncertain at this point.  There are two main reasons that it's uncertain: you did not mark CF after CD 16 and you didn't log a temp on CD 15.  Also your temps are a bit erratic here and there obscuring your spike.  If you disregarded CD 9's temp your temp pattern would indicate O on CD 13.  But with your fertile CF that came after that, it's unlikely.  So FF is searching for the next clear spike, but none has been confirmed yet with three high temps.  It would really help if you could recall your CF on CD 17 and 18- was it drier?  In all likelihood, CD 16 will end being your O day, but it's just not confirmed yet.

And keep in mind that OPK's are not very reliable for a lot of women.  The monitor has better ratings, but again, your temp and CF are your best indicators and more data is needed at this point.
