Too early??

Meagan
So I've been feeling weird lately.. Normally I get a day or cramps two days before my period, lower back pain the day before then AF is there first thing in the morning, some mild cramps && moderate flow for four day.. Now AF isn't due for 6 days (9/23) but since one week after my fertile week (which I BD every day that week) I've had this dull ache cramp feeling every day since... && I'm nauseous when I cook anything, but wanna eat half the fridge... Is it to early to test?! I want go but don't wanna be disappointed... Help?!
