Holy F Shit I have never had implantation bleeding IS THIS IT?

I’ve had 3 pregnancies, zero implantation bleeding. Like literally never even a spot. I’m 10DPO today. Took a FRER this AM that was negative and I’ve always had a positive one by now so I counted myself out. But I just wiped and had this

I have a perfect 27-28 day cycle and literally have never ever spotted in between unless I was on birth control. I mean I guess it could be something else going on? Idk help me also please ignore my nails.

Also how soon after IB did you get a BFP if you had it?

Thanks in advance!!!
