Just wanted to add that you'll usually get your cover line and ovulation date confirmed after you've had three higher temperatures in a row. Best of luck this month!
Charting alone dosn't predict ovulation. BBT is used only as a back up reference of O already occuring. You still need to do your OPK, thats where you actually get your prediction. If you don't have a surge, like your doing meds with the doc, your trigger will determine the day you O, Hope this helps a little.
