DPO 13 & BBT Steady

Could it be? We took another HPT this morning and the "test" band was faint. So not positive and not negative? We're trying a new HPT from here and they are not the most intuitive test to interpret. But, on their website in the FAQ section it posts the following:

Q: If the test band is faint, is the pregnancy test positive?
A: positive result will always be indicated by the presence of a distinct color band in the 'test' region of the pregnancy test strip or midstream test (accompanied by the presence of the 'control' band). If the test is faint (in comparison to the control band), the test may be positive, though the presence of hCG in the woman's body - or urine sample - may be low. The presence of hCG doubles every two days in a pregnant woman. In cases where a faint test color band is present, we recommend that you retake the test the following day using first morning urine. Again, following test instructions is critical.

So, we may be reaching here, but that translates to "we could be and the H's HCG may just be low". Here is why I think we might be:

• H's BBT Dip on DPO 10 could have been the "implantation dip"
• H's BBT is staying steady above the coverline
• The "test" band on the first HPT on Thursday was very, very, very faint. We both thought that maybe we just "wanted" to see a band but it wasn't really there so we dismissed it.
• The "test" band on today's HPT is still faint, but definitely noticeable

What does this translate to? We wait. If AF doesn't show up by Sunday Morning and H's BBT remains steady, we test again on Sunday.
