Spotting and then your period comes

Kristin • 👧👼👧👼👼👼👼

My husband and I are TTC #3. I went off BC in early June, but I wasn't doing much to track things until recently. Five days ago I had 3 consecutive mornings with very light spotting (light pink). Yesterday there was nothing. Today I got the normal red flow where tampons were needed. I had originally thought implantation bleeding, not now I'm not so sure. I wasn't due for my cycle for another 5ish days. My cycle doesn't seem so regular, but the spotting has me questioning. Has anyone ever had this happen to them? TIA
