Early period

Hi everyone, so my period usually occurs every 30-35 days and sometimes it comes later than that. I had my period November 21-26. Skipped my period in December. Got my period January 2-6 and AGAIN January 30 - Feb 4th. (And spotted for a few days even before that) It was really weird for my period to be early cuz that never happens. I had protected sex with a condom and pull out combined on January 15th. This was the bleeding I experienced. I was overthinking what if it was implantation bleeding but like I said. I had protected sex.. Please let me know if I’m overthinking
