January 23, 2017 at 2:38 amHello, I'm new to this community. This is my 4th month of TTC. The chart is very useful but I am confused about the day when the temperature shift really happened this month. I thought I ovulated on cycle day 14 as I had strong ovulatory pains that evening and the following day my temperature raised. The chart, however, considers day 17 to have been my ovulation day. Not sure what to think. We stopped BD on day 14... and now I'm afraid the following two days would have been the most fertile ones? Please advice. Thank you.
