Is this considered my period?

Alana

I’ve been tan/brown spotting for over 24 hours and no red or flow and it’s just when I wipe… I started inositol this cycle and I’m wondering if this is a light period due to the medication. It came right on schedule for my period. We are trying for a second child and I’m on tons of supplements as is my husband so I’m tracking everything and doing OPKs and I’m just not sure if I consider this cd1 and cd2??? My easy@home tests are negative so I don’t think I’m pregnant fyi.
