the wait is killing me!

Kaitlyn
6 days until glow says my period is due. I believe im 13DPO. I took a test a few days ago, and it was negative but i want to take that second test so bad! Im so im so impatient i might die! 
Symptoms: waking up nauseated, vomiting occasionally, been having very mild cramps this whole week that come and go, hot flashes, my boobs feel bigger, sharp twinges of pain in my nipples lol, increased urination and frequency, food cravings and aversions, fatigue, nauseated on and off throughout the day, andincreased thirst. 
What do you guys think? Im concerned about the mild cramping. Does that sound like it could be implantation cramping? No IB. Just cramps.
