Very Confused..Help!

Hi everyone!

I got my first positive on a clear blue digital on Monday, and have tested every day after but the lines were all faint with the exception of a couple that were a little clearer. My period was supposed to come today and didn’t, but last night I had some brown spotting/discharge and today I noticed some bleeding mixed with mucus when I wiped. I almost thought I was getting my period but it wasn’t like my usual period and was lighter. My last period was on May 10th, I had sex a day before ovulation on May 22nd according to the FLO app but I’m not sure how accurate it is. I’m very confused if I’m having late implantation or if I am pregnant but having some pregnancy bleeding. Can anyone offer some insight? Thank you! 🙏♥️
