I'm so confused. I had a 31 day cycle last month. I had a blood test on CD 22 to test for O and it did happen. I asked when and the Doc said she could only say in the 7 days before. My period tracker said O was CD 21 but it only works off dates of periods, not temps etc.
I don't know if I have enough DTD coverage as we BD 17, 18, 19 and 21.
CM was EWCM on 18 and 19 but I didn't have any twinges etc.
When would you DTD? And how often?
