Cervix Change!

Wondering if its me or if anyone else experience's the same thing as me.
It seems that at different times in my cycle like right now that intercourse almost feels like its hitting a wall inside, were as right after AF and up to a few days ago everything was fine. I should be approaching ovulation about now to the next day or so but i would think if my cervix was high like it should be I would not be feeling this. Maybe its just me.
