Ovulation test?!

Has anyone else had trouble with ovulation tests? I have been doing the tests for two months now and the first month I did just clearblue and this month I added wondufo. For both months the clearblue said I was ovulating 2 days after my period. With PEAK FERTILITY it says. ( I just wanted to track exactly the increase in LH). I have been off BC for 2 1/2 years. I have regular periods that are 24 days. Anybody else have issues or advise?
