Pictures Of Cervix Before Period Question About Cervix?

Question about cervix? - pictures of cervix before period

My question after the cervix is as follows:
Should it be in the middle? When I put my fingers in my vagina, it is my neck on the left side of the upper part. Well, I tried some research and look at pictures, and as always in the middle. It never bothered me before, but the reason why I'm so worried because I'm pregnant and I'm not sure how all its gonna be fine if I am at work.
