Those are pretty wide ranges. In your shoes, I would use the number for the luteal phase, but even so, 22 - 256 is such a huge range that 49 might have even been normal for you when you were having periods.
Anyway, ask your ob/gyn to refer you to a specialist to see why your periods are AWOL, no matter what your readings are you already know that they are not coming on so it's not like you need proof.
