Do you usually bbt chart?
If so, is your thermal shift always this late in your cycle? If it is, I would think that is a problem and you should discuss it with your DR or RE.
If this is a random occurrence, I would guess that you will start AF about 14 days after ovulation.
You can also get false + OPKs if your urine is too concentrated.
If you are new to bbt charting, you are looking for trends. If there is a random high or low temp mixed in where it shouldn't be, you can usually disregard those. I've also seen others post about implantation thermal changes, but I don't know much about it. If you usually have a 26 day cycle, a thermal shift around cd 19-20 would be around the time of implantation, if you are PG?? Something to think about... Best of luck to you.
Thanks for the info. This is the first time I have tried charting so I am not really sure if this is the norm. I can't think that I am pregnant because I haven't been maintaining high temps. I'll keep mointoring next month and see if it reoccurs and if so go see my doc to discuss.
Thanks again
