Does cervical length matter at 8wks?

My cervix measured 2.7cm , doctor didn’t mention any concerns , but when you look it up (thanks Google😒) , it says cervix should be 4.1cm (41mm) at 8wks. Should i be worried? My first pregnancy was great, actually carried a week over before i was induced.

Please no negative commentary , i have anxiety and just want to know if it means anything at this stage in pregnancy or not, if there’s any reason to be concerned, others similar experiences , etc.
