Sometimes your breasts will change size a little bit during your cycle. They might swell up more before your period, for example. I have been noticing that I keep cycling between 30.5" and 31" but I am right before my period so that may be why the extra .5" even though I only started NBE a week ago and have only been massaging so far. It might also be where you measure - if slightly lower or higher on your body, it might change the measurement very slightly (which might be the case for me too).
