Tested this morning on day of my expected period; I only have digital with the weeks estimator. Hubby is cautiously optimistic, but thinks this could be a false positive and wants me to pee again tomorrow with another CB weeks estimator. Should I do it again tomorrow or wait til next weekend? I'll be calling my OB for my appointment on Tuesday when their office opens again.
