Cramps 5 or 6 days before AF

Virginia

I’ve got cramping in my lower back and for the past three days I’ve been SO tired. I usually only get cramps 2 or 3 days before AF. Yesterday I fell asleep on the couch at 8 pm. Anyone have cramps before their BFP? I’m really nervous because I had a chemical at the end of May. I want so badly to be pregnant but I don’t want to get my hopes up.
