Pre-period spotting

Stacy

My husband and I have been TTC since I stopped the pill in February 2019. I’ve recently returned to regular cycles but still have spotting 3-5 days before my cycle fully begins. Should I be considering the brown spotting to be my period, or do I wait until AF obviously shows up to consider that CD1? I have used OPKs in the past that show surges but we just haven’t gotten the BFP yet :(

Any thoughts?
