Confused (TMI)

[Angel022605]

I'm on cd 14(9-28) and I'm due to ovulate either today(9-28) or tom(9-29) and my cm is very dry which normally by now I get loads. My cervix is high hard and possibly either slightly open or tilted back(can't tell) and normally it's high and soft. What can cause this? I know antihistamines can cause a decrease in cm but that's never affected me. I'm always well hydrated. Can anyone help me?

Any advice/answers would be great
