Has anyone ever has this before?

I had a miscarriage Oct 1 bled for 22 days Nov 2-5 I had spotting to med flow it didn't feel like a period at all. These are my ovulation test for Nov 17-18-19. I'm really confused. Idk if the 18 test was a bad test but glow stated I'd ovulate the 18 but got to positive ovulation 17/19
