Help Please

Erin • Celebrated 5 years in November. Expecting our first Jelly Bean September 2016 ;)
I still have a few days before I can test. My period isn't due until the 15th. Today I feel terrible. I tossed and turned all night and today I am so nauseous. If I am pregnant I am only 3 weeks and 2 days. Has anyone had symptoms this early on? Please help.
