Implantation bleeding????

I’m 26. I NEVER have spotting before my period, but today, 6 days before my period is supposed to start and about 9dpo, I checked my CM and there was good bit and it’s a nice light pink color. I’ve also been cramping pretty bad today, but I have been cramping almost a week before my period the last few cycles. My periods are very regular and so are my symptoms. I am NOT ttc, my man is trying to finish grad school first 😫 but could this be implantation bleeding??

We use condoms, but right around my ovulation we did go at it for a minute with no condom before putting one on. So precum would be the culprit, but that’s so unlikely...but not impossible. Any experiences you may have had would be great to here!
