I tried it all.
Keeping track of temp was fairly accurate showing day of ovulation - but didn't make up for the fact that (despite what they keep saying!) sperm really must not die out by the 5th day.
I have a medical condition that has hindered the ability to properly read the sympto-signs.
So basically I'm left with celibacy.
You are in my prayers.
God knows your efforts and your struggles. I pray that you find peace and comfort in Him.
I am really, really sorry. You have a great cross indeed.
