Implantation bleeding or irregular period???

[klb12]

I'm currently nursing my 9 month old son and I recently started my first pp period on April 30th. On cycle day 22 I had super light spotting and it was only once when I wiped and then cycle day 23 it was just a tad bit more like maybe 3 wipes. It was like a light reddish pink stringy mixed in my cm (sorry TMI). It completely stopped and hasn't been back then cycle day 24 I had cramps. Not regular period cramps but I knew they were there. They were extremely light and didnt last long. I've already taken two test both BFN which I know its to early just exciting myself and I went out today and bought some of the more sensitive test. I have this gut feeling I could be but idk if it is because ive been reading all over google about implantation bleeding and getting excited or if i really am. With my son I had no symptoms at all I was just late and tested. I have also never spotted before. Is this implant bleeding or maybe just from my hormones from breastfeeding. And has anyone else ever gone through this???
