the condensed version of this month is:

AF is 10 days late, but all HPT have been negative, and so was the blood test i had done at the doctors

up until now, my cycle has been a pretty picture perfect 28-29 days, and the OPK i took this month showed ovulation at the "right" time (it matched every other month)

has anyone had this happen? i'm worried about what else might be going on if i'm not pregnant, and AF has gone missing - i have a dr's appointment scheduled for next week, but am a little nervous
