I did alot of research on this.
During AF - Low, soft, open (i think open due to the nature of af)
After - Low, hard, closed
A couple of days before ovulation - Starts to get higher and softer
Ovulation - Very high, soft, open
After ovulation - gradually gets lower, harder and closed.
Then the cycle repeats.
You will get a lot of conflicting veiws on this as everyone is different. For example, I was ovulating around 30 May and my cervix was high and soft. Its now June 5th and af came yesterday (2 weeks early) and my cervix is still very high and soft. I'm very confused!!
Best thing to do is feel your cervix everyday and log how it feels. Its not that uncomfortable. Do it at the same time everyday and in the same position.
Everyone is different by after a few cycles you will know whats 'normal' for you.
Hope i helped!!
