I have always had regular periods (pretty much) and I had a very short one (4 days) on march 3-6. On the 11th I got what I think was a positive ovation test (see picture it is the strip!) but all my digital were saying high, never peak. Then it went to nothing. Well... I had weird cramps. And logged it in glow and it said I'm having ovulation cramps. I'm like ok. I'm 7 days away from my period, no way.
