Until AF shows, there is still the possibility. Some ladies just test late.
Did you do anything this past cycle that could have extended your LP, though? For example, I took a B-Complex vitamin that extended my LP by two days, so that could be one reason for the later period. Or, is it possible you O-ed later than you think you did this past cycle? Maybe you aren't as far along in your cycle as you think?
