Anyone’s period changed ever changed?

Melissa

All before, my entire teenage years I’ve had a regular cycle up until the age of 22. I’m 23 now. But It would fall on the same day and last the same time. From the 18th of each month until the 25th NOW

It’s completely shifted to starting at the 5th of each month until lord knows how long lol

My doctor said it was normal but I want to know if anyone else had this issue?
