Am I prego?

Drea

So my last period was last year December 14th 2018, it's going on the 22nd of January 2019. I was supposed to start January 13th but it never came.. I'm having serious cramps sometimes it's light sometimes it's heavy on and off for about 5 days now. And my boobs are very sore every once in awhile I have a burning sensation and then after my nipples will hurt could this be a sign of pregnancy? What are some early pregnancy signs?
