10DPO

FertilityFriend is not my friend. It's telling me my cycle length is 31 days, which it never is, and that O-day was CD16, which is later than I expected. Therefore, according to FF, today is 10DPO, but I shouldn't test until next Saturday... I am impatient, and I'm going to go to the drug store and buy some tests anyway. Yup, you heard it here first. Granted, AF is supposed to arrive tomorrow, but still...
