High hard closed cervix. Is that how it should be before a period? - cervix right before period

I know that the cervix always changes throughout the cycle. My boyfriend regularly reviews the neck. I always thought it was really strange, but since I was TTC I thought I should.
How is your cervix will feel before a period? Mine is about 14 or 15 years and it is hard and closed.
If so, how should it be?
