Looks like you are gearing up to ovulate! They say the "normal" time for most women to O is CD14, but it is really variable from person to person. How long is your cycle normally? If it is very routine at 28 days long, you may be one of those rare "normal" people
A lot of women have a dip right before or on the day of ovulation so that could be what your temp drop is about. Since you're having fertile CM, I would consider it quite possible that you're going to O soon and get to the BDing!
Good luck
