Too late to be implantation bleeding?

Rebecca

Hi guys, been having spotting light pink for the last three days just on the first wipe of every day, tmi I know, starting on cycle day 25, now on cycle day 27 and AF is due tomorrow. I never ever spot before my period but wouldn’t it be very late for implantation bleeding, and if it was implantation bleeding how long would I have to wait to take a test 🙈 Thanks in advance ❤️
