Cervix?

Has anyone else felt their cervix?

I’ve been able to feel it low and firm for the past few months. Then last night I could barely feel it with my finger all the way in, and since it was so high it seemed soft. I’m 18weeks 3 days. I message my office last night, and will call them later today as well, but just wondering if anyone has noticed a change in their cervix I. The second trimester. I have no spotting, changes in discharge, or any different pains then I’ve been having.
