I would sign up for a membership at fertilityfriend.com. You can record your temps there and it will give you red cross hairs when your temp spikes up. You do need 3 days of consective high temps in order for you to get the crosshairs but it takes the guess work out of everything. Here is a good guide to go by for when you will O based on your Cue Peak.
When your cue peak is on day 4-5.....you will O on day 13
When your cue peak is on day 6-7....you will O on day 14
When your cue peak is on day 8-9.......you will O on day 15
When your cue peak is on day 10-11.....you will O on day 16
When your cue peak is on day 12-13 ....you will O on day 17
