What is going on?!?!

My period is theoretically not due until June 2nd, if it is "on schedule", but on May 22nd all throughout the day I had a slight pink hue whenever I wiped and it was only CD 22. Yesterday morning right when I woke up it was bright/deep red with a tiny clot or two when I wiped but nothing but a slight brown discharge after that. Nothing really has made it to the pad I was wearing because I thought it was my period.  I am new to finding out I have PCOS and am wondering if this is normal or maybe some possible ideas of what it could be. I don't want to panic everytime something "weird" happens and it turns out it is normal for PCOS. I have heard of implantation bleeding before but seeing as I have PCOS I am not quick to jump to that conclusion right away cause I am sure it is unlikely.
