Should I be concerned?

I have an appointment with doc this week. Just wondering if anyone has any insight as to how/why I could have my “period” 3 times in one month. I started Nov 13th, 30th and then Dec 12th. My periods have always been regular and my cycle is about 30 days. This is more than spotting, it’s definitely like my regular cycle. Any advice would help :)
