Tracking ovulation w/glow

Tara
Sine my MC three  cycles it seems like my ovulation has been wacky, nothing the first cycle maybe something last cycle, and definitely something this cycle. I JUST ovulated about ten minutes ago (I can always literally feel the pop, along with track my CM, OPKS and temp). last cycle was also late in the game by about a week, same as this one. But my period showed up right on time, as scheduled.
​This month, I've had three days straight of positive OPKs, all showing right AFTER my predicted fertile window ended. As soon as I entered the first, glow automatically adjusted my window to include the next couple days in my window. Today was my first non-fertile day after. But when I entered a positive OPK today, it didn't adjust my window  again! 
​So far from what I can tell, I'm ovulating about six to seven days late, even though my period is regular. 
​My question, is should I plan to BD or an entire two weeks next month, or just plan to BD a week after Glow says? I travel for work, so I need to figure this out.
