AF was due today but no sign of her yet. My nipples hurt so bad when I woke up and even hurt when I tired to take a hot shower. That all stopped about two hours later. But I've been having to per every 30 mins to an hour! Could this be a good sign or a sign of aunt flow? I also checked my cervix and read that if your finger can go all the way in to the third knuckle that means your cervix is high. Is that true?
