Low cervix?

Ok I’m 6 weeks pregnant this is my fourth pregnancy and my cervix felt a little higher last week and this week it’s really low I have no bad signs no cramping or bleeding just seems weird that it’s low it’s soft but lower like I had a lot of extra CM is only reason I felt for it just idk out of curiosity but I’ve heard some don’t move up until close to the end of first trimester but I’ve heard too that it could be a incompetent cervix idk I’m worrying probably over nothing I mean I feel ok just worried why is it low still? Anyone else have a lower cervix during early pregnancy and all was ok? Or is it normal for some women to have a cervix that can change at different times sometimes low sometimes higher? I go back to the doctor Tuesday so I’m going to ask them then about it but just wanted to see if anyone could ease my mind about this or have any experience with this good or bad. Thanks ladies I am really excited for this baby and I hope all will be well I’m nervous because it is my fourth child and it’s been ten years since my last one so I’m just nervous about everything.
