Is it possible to skip ovulation

Di
I have been <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> just by temps thru Glow and it seems that I have been ovulating since I started in November.  This month I got First Response ovulation kit and I still have not gotten a yes.  That's starting to worry me and I was wondering if it is possible to skip ovulation certain months. Thanks :)
