Your cervix is normally about 2.5cm long. So if your cervix is only 1cm then you are about 75% effaced. Don't forget this is only an estimate as the normal length of a cervix can be a little different from onw woman to another
Mine was measured at a scan 5 weeks ago and was 1.6 how effaced would that be around Alan LOL
