Out of HCG tests

THREE DAYS LATE (I'm usually early NEVER LATE)

Brown spotting off and on

High cervix (no other symptoms)

I keep cramping and running to the bathroom to check, but nothing's there.

I've been TTC 19 months and I don't want to get my hopes up :( I don't even have HCG tests for that reason.

I took two LH tests with VERY DILUTED PEE (it was seriously almost clear)

Has ANYBODY had this happen and been pregnant?
