AF cramps entire week before BFP?

Marina

My AF is 6 days away. I’ve had back pains for days now - about 2 weeks before AF. I’m now having cramps that started yesterday, but AF isn’t for 6 days. Did anyone experience continuous backaches and cramps for 2 weeks before AF and ended up with Bfp? The cramps are definitely becoming stronger, and it’s discouraging me :(
