Could I have ovulated so early?

Question

So this is our third cycle TTC. I used the Clearblue advanced digital OPKs my first month and got one low (first use) then 5 days of flashing smileys, and I got peak on CD16. This month I started testing on CD13 bc according to glow it was one day before my fertile window was set to begin. Well I have had 4 days of low fertility (blank circle) so far and I’m worried that I may have missed my chance this month (we did BD for fun on CD8 so there’s maybe a chance there). 
Glow moved my ovulation day to this Friday now and I will be out of the country visiting family for 4 days and my hubby wont be going with me. My question is, could I have ovulated so early? Or maybe I’m just ovulating late this month? I’ll keep testing 🤞🏼Ugh my hubby and I were so determined to make a baby this month and now I think my chances are not the best. I was looking forward to a Christmas announcement for our family and friends.
Side note: I have regular 30-31 day cycles and Glow always estimates my period correctly.

Answer

So I originally thought my cycle was 28-29 days. This was with 4 day periods. My fertile window starting about 7 days (CD 11) after my period ended. Ovulation about 5 days (CD 16) after fertile window started so on and so forth (according to Glow app). 
I felt like I was missing my ovulation as well. I was using OPKs and ClearBlue Advanced Digital Monitor, and those results were always low/no peak/etc. for a good 14 days😕. Then boom, period again. 
These last 2 cycles I started using my OPKs and ClearBlue Advanced Digital Monitor the next day after my period ended. Thank goodness I did!!!
It ended up that my fertile window was starting 1-2 days (CD 5-6) after my period ended with ovulation happening about 7-8 days (CD 11-12) after my period ended. 
So when I started testing OPKs some 7-8 days later when I was thinking my fertile window was starting, I was missing my high/peak results and was already going into low results, never rising, indicating my ovulation passed.
The first cycle was a test to see my timing, and hubby and I didn’t get to BD as much. This 2nd cycle I was on it! 😂 And sure enough I got my high results CD 8 & 9, peaked on CD 10 & 11, high results CD 12, then low results CD 13-17.
Once I entered this all into Glow, it adjusted my entire timeline/calendar 1 whole week earlier!!
I would have not figured this out had I not taken upon myself to just start testing the day after my period ended. 
Hope this helps give some insight!! BABY DUST ✨✨✨
