Cramping 7 days Before AF

I never cramp this earlier. I've also having really bad back cramps as well. My face has broken out worse then it has ever been, and I feel like when I pee it's the longest pee ever. Plus I'm having really bad headaches every other day, along with really bad heartburn and nausea at about 3am-5am. I took a test this morning and it was negative, I'm 6 DPO. Did I test to soon?
