Is this a good sign??

I’m 6 DPO. And last night I felt really tired but as soon as I laid down my heart just started pounding like I was having anxiety when I wasn’t. Today I have noticed some slight cramping on and off throughout the day, I’m having hot flashes when I like never so unless I’m dehydrated and your girl has been drinking water. And then last night I seemed to have a wave of nausea that only lasted for a bit and then again today after I ate. I’m really trying not to symptom spot but I can’t help it😫😫 anyone else have this and ended up with a BFP?
