My research of FAM has lead me to believe that while ovulating your cervix is more 'open' and squishy, and that it returns to being firm and 'closed' once you're no longer fertile. How reliable is this?
From all the FAM research I've done (relied on it as contraception for 4 years), cervical position can be used as a secondary indicator of fertility, meaning it can be used to confirm cervical mucus and/or BBT, but it's not truly reliable on its own.
I know that my cervix generally gets higher in my vagina near ovulation, but this doesn't always happen. And it often closes tightly after my fertile time has passed, but again, it doesn't always. Whether I really feel it become more open during menstruation depends on whether it closed up tightly before.
If you're curious about this, try tracking your cervical position every day for a few cycles to see what's normal for you. (Though I wouldn't depend on cervical position alone as a contraceptive technique.)
