Hey hun first off how regular are u cycles ?? A normal 28 day cycle should average around a cd14 ovulation so every day u add onto ur cycle ad a dsy onto ovulation my cycle is 30 days and I ovulate cycle day 17 the opks are just there for people ttc to get the positive go ahead hun so don't worry ... as for checking cervix .. when you are fertile ur cervix will be high soft and open and as u nesr ur period it will come down and be a little more rough and closed however I've heard if u fall preg ur cervix will stay high soft and closed which mine seems to be atm
also cm is a good indicator u shud start with dry after your period and then it should become creamy then to watery then to eggwhite and stretchy very fertile !! Then back to watery then to creamy then dry up before period !! I hope this gives u some insight if u need time to help with anything I'm right here hun xxxxx
