Spotting!!! AF or implantation?

Jordan

Three days ago at 8dpo I spotted while I was going to the bathroom (BM) and it was a very bright red blood with CM but it wasn’t a lot(mostly sticky cm). I also have been experiencing mild cramping on and off since 5dpo. Since 9dpo I have been having pink and orange cm... I usually do spot before AF arrives but it is usually a constant red spotting without cm. Does anyone believe this could be implantation or is it actually just AF making her arrival. I have sent my fiancé to the store to get some tests but I would like someone input please!
