TMI period or possible implantation?

So this is our first month TTC I got off of my BC at the end of April. My periods before BC pills was like clock work every 10th of the month on the dot. But my BC pills made me miss my period while I was on them. After I stopped I got my period on May 1st not my regular cycle but I guessed my body was adjusting. I did not track ovulation during May so I have no idea when I ovulated but my SO and I BD every other day last month.

Well the 1st of the month came and no period and I’ve been taking pregnancy test ever since with nothing not even a VFP. Last night I went to the restroom and when I wiped there was a little blood on the toilet paper. I thought AF is here I inserted one of my 12hr flex disc and went about my business but today when I went to change it nothing the disc is empty. when I wiped after taking it out there was a little spot on the paper. I’m so confused is it AF or could it possible implantation? I placed another flex disc in and I will see what happens in the next 12hrs if the disc is empty again I will take another test in the morning.
