What does this mean?! Confused!!!!

Since I got off my period I have been doing cervical checks! While I was ovulating it was high wet and open like normal, then a few days later it went down to closed medium heighth dry and hard, then it went to low hard closed and dry then it was low medium firmness and low. Well today when I checked it was low soft again and closed. I've never done cervical checks before I was wondering if this might be a sign of pregnancy or if it is just a normal cycle? Anyone know?
