Did you just know you were pregnant?

Savannah

I’m 10 dpo today and got a negative test but I just feel off this month. A few days ago I woke up in the middle of the night feeling nauseous then had some hot flashes the next day. Had some cramping yesterday with back pain and a few small cramps here and there today. I have had an increase in discharge and sex drive and even though I got a negative I just feel pregnant? Did anyone else have something similar? 5 days until AF
