Hi and

! I am using OPKs and temping this month too. I really like it! My cycles are usually 28 days, and though I knew I ovulated later, I discovered this month that I didn't ovulate until CD19, putting my luteal phase at just 8dpo. That is if AF arrives on time. After my chemical in December, my cycles got a little weird. But I should be back to normal this cycle. I have to say that I like charting my CP/CM, symptoms, temps, etc. It gives me something to focus on each day and has gone a LONG way towards helping me not obsess over pg symptoms.
Also, you may want to consider prenatal vitamins, Evening Primrose Oil from start of AF to O day, low dose or baby aspirin, as well as Vitamin B to help lengthen your LP if it's short. There are also Fertilaid vitamins that you can take, as well as Preseed lubricant you can use to help around O time. There really are a lot of things you can do to help the eggie along. Lots of Baby Dust!!!
