Tracking ovulation by checking cervix.

AFwife

We have been Ttc for 9 months now. I’ve been <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> by checking my cp and cm. Once I am in my fertile window my cervix rises, open and softens which it’s supposed to do. But last cycle and this cycle is hasn’t done that. Does that mean I haven’t been ovulating? My period was only a day late last month but other then that my cycle has been pretty much the same. Any advice?
