Confused…

Shakkia

My period is due 8/25. I had unprotected sex 8/15 and again 8/16. Tonight as I was wiping I noticed light pink spotting. I have never started my period this early before. It’s cycle day 28 and I always start cycle day 32. Is it possible that it’s implantation bleeding?

Update: I went back to check and nothing. I’m no longer spotting.
