Ovulated already?!

Kathryn
BD again tonight or have I ovulated already? Woke up an hour early this morning and temped before I knew what time it was. That temp is on the chart. When I woke up at my normal time, took temp again and it was 97.72, the same as my highest temp this cycle. Last month I got my first +OPK on CD16 and my BBT rise on CD19, this time +OPK on CD13 and first rise on CD15. BD again tonight just to be sure and hope for another temp rise tomorrow morning?
