Need advice with cycle


Hi ladies. So my last cycle started on May 8-12, and a week later May 21-25 I experienced light daily spotting which never in my life happened before. My cycles are a little longer and range between 33-43 days. Today is MY LONGEST cycle every, I’m at day 47 now from first day of last period. Why is my cycle late this month and why did I spot like that a week later for a week? Has this happened to anyone?
