Implantation???

Sorry for tmi

On Tuesday when I went to the toilet I noticed like a small amount of brown discharge (probably old blood) in my underwear. That was it. Then Wednesday when I went to the toilet and wiped i had a tiny amount of that again and that was it. I’ve had nothing since. I have been experiencing mild cramping/pain. I’m currently 10 DPO and AF is due Tuesday according to glow

Is this implantation??? I’m trying to hold off testing until AF is late, if she is
