Not my normal period signs

Abby

Hopefully someone can give me a little insight. AF is due in 2 days, normally about a week before my period I have my normal symptoms. Sore breast, lower back cramps, irritability..etc but this time all I have is sore breast and a few days ago I was experiencing a tight tingly cramping sensation in my lower abdomen. I got a little overly excited so I took a clear blue digital test of course BFN. Am I just experiencing an irregular cycle or is there a possibility I’m pregnant and just have to wait to test again?
