Possible Implantation???

So, glow says I ovulated sometime between the 23-28th. My period is not due until the 10th. I had spotting on the 30th that only lasted for about 5 hours or less. I saw it 3 different times when I used the restroom. I thought it was AF showing up way too early because I have had 2 periods a couple weeks apart before. Anyway, it was light brown mixed with some clear discharge the first time, second and third was a light pink. All only present when I wiped.

I’ve also had very, very slight cramping every now and again. I was constipated at first, then had normal BM, then Diarrhea. I felt like I was smelling burnt food in class but no one else could smell it. Is this possibly my BFP??? Or am I crazy???
