Cervix Question

Hi ladies. I'm 19 weeks and noticed that my cervix feels very very low. The only reason why I checked it (i know you're supposed to stay away from your cervix during pregnancy) was because I had sneezed and literally felt where my cervix was sitting. So when I checked it I only had to go in about a half inch at most in order to feel it. I haven't had my anatomy scan yet so I'm not sure how long my cervix is at this point. I know before pregnancy my cervix was always low even while I was ovulating, so maybe it's just my normal as I'm having no pain or bleeding or anything concerning like that. Just wanted to see if anyone else had any insight or experiences to share on the subject. I did talk to my on call dr and he was no help at all.
