Any suggestions??

 TTC, 35 yrs old 
I had moderate endometriosis (laser surgery in OCT) blood work showed low progesterone 
Dye test done & tubes they're good 
Dr has me on 100 mg of Prog 1st half of the cycle & 200mg 2nd half of cycle 
Any suggestions to try to increase our chances of BFP?! 
It's hard not to be discouraged when it isn't happening
