Late Period, No PMS symptoms

So I’m late by 5-6 days, usually my breast hurt and are tender, I’m bloated,and I’m cramping, etc..... Well today I’m having lower back pain and I’m cramping (light), my boobs only hurt near my armpit area and that’s it, anyone have this experience before and got a BFP or what was the result? We’ve been TTC for 2 years.

Also: I took a test 2 days ago and it was negative!
