Ovulation Tests

Miranda
So, I stopped taking the pill about 14 days ago. This app says I should be ovulating and I have taken ovulation tests for the past 3 days and nada! Are these tests really accurate. I feel like I don't know my body at all bc I've been on BC for about 15 years and I don't know if I "feel" like I'm ovulating...does this mean I'm not dropping eggs or are these tests crap?? Thanks in advance!
