has anyone felt like this at 6dpo?

I am 6dpo today according to glow today I have been Feeling achy in my legs and back like I just ran a marathon or something it really hurts even just to walk around I just feel like I'm coming down with the flu but I don't have a stuffy nose or anything I have experienced a little bit of a sore throat I haven't really had any symptoms I had a wave of nausea yesterday while eating but it went away after awhile I've also had a little bit of cramping nothing much tho has any one else felt like this and got their BFP??
