Possible implantation bleeding??

Krissy

So since yesterday which was CD25 out of a cycle length of 30 days I've had some inconsistent pink spotting. I'm 5 days away from been due on. What's the likely hood of it been implantation bleeding? I've had no cramping along with or anything. My other half is putting it down to the fact my period is going to arrive early 😢 Tia
