Trying to conceive.. confused about ovulation timing

Melissa
I finished my birth control pills on Sunday June 5.. BUT I had been spotting since May 23 (no idea why..stress?) Had my so-called period from June 7-9. The Glo app says I should be ovulating from June 18 to 22.. just took an ovulation test and it was negative.. what might be going on? Anyone else have this happen?
