Period??

Supposed to start my period today!!! Boobs have been hurting very badly for the past week, my back hurts very bad, and I’m super tired. Not sure if these are signs that period is going to come?. I want to test but I feel like i should wait a couple more days. Don’t wanna get my hopes up. 😬

UPDATE:: sooo I’m currently a day late! Took a test and got a BFN....🙁 is this normal? Could it not show right now? My boobs still hurt extremely bad, anddd I ate tbell today and it made me a little sick. Help!
