42 try to get pregnant

Sh
I am trying to get pregnant at 42 but it isnot happening. I have done all the tests and looks good except the FSH level is 10.3 which my doctor told me is better be less than 10. Also i have burning pain on my sides specially left side which i never had it before. Acctuly the pain starts 10 days before my next period. 
Something happening inside me, I don't know what.  
Anybody has anything to tell me to help?
