Period is LATE!

Hi friends! I for the past 3 years, have gotten a period every single month, never missed one however my last period was at the end of October and it’s been almost 50 days since. This past Saturday, I wiped and there was blood. I thought it was my period but the next day it was gone. I thought I had started my period but it was just one day of spotting. Keep in mind I have never missed a period so this is really strange. Do you think I didn’t ovulate in November? Someone please help me because I am beginning to worry. Thanks I feel like another period is going to come at the end of December, but any answers or thoughts would be sooo helpful!
