Beautiful cervix

Lisa • Married 5 years to a wonderful man. Son born 26 Jan 15. Expecting another boy in Nov 16 X
I check my CM by doing a cervical sweep daily.
​I read that cervix should be soft at the time of O , typically my cervix doesn't go soft until just after O and then hardens around 4 DPO - is this normal?
​I determine O my using OPKs, CB Monitor, CM checks and bbt
​Just curious - thanks ??
