Implantation bleeding?

Sierra

According to glow I ovulated on the 19th of this month. We baby danced on the 18th and 15th. My period isn’t expected until the 3rd of February but I started having light spotting last night and I still have it today but it hasn’t gotten any heavier. It’s gone from light pink to reddish pink and now back to pink. Could this be implantation bleeding?
