Hi Michelle,
I wanted to just reply as it sucks waiting for someone to write when you are waiting with anticipation.
I don't know if i can help you with anything other than encouragment. I have endo too but my cycles are regular 28-30 days in length. I do want to ask though, Where is it painful? And ovulating this late in your cycle make the cycle how long?
I know my cervix get quite tender before ovulation and if my bowels are full that hurts too. i do know that i was having painful intercourse...and therefore not having it...when i had a cyst that was large enough to create pressure. It was leaking into my abdonmen which was not great for me.
We have been trying to fall preg for about 8 years now with no luck so far. I have a good feeling about this month.

I wish you all the best and hope you find the answers.
Jodie, (HIppy Mum- to be)
