help? SMEP

Je
We lost our baby when I was 17 weeks preg. I had a d&e so I have no clue if the glow ovulation is right or not but I plan to use opk to confirm 
I want to use the SMEP as it was designed for women like us. Problem is I don't know how to follow it as it goes against what glow suggests and I don't want to miss anything 
The plan says to BD on CD8 which is 25th. Then every other day till you get a positive opk. You begin opk testing on CD10 which is the 27th for me. Once you get a positive you BD every day for the next three days then skip a day then BD one more time. 
Glow says my best chance to conceive is the 31st. But that my fertile window starts on CD9
If you are still reading and I haven't confused you. When would you BD and test with opk kits?? 
Thanks !!
