Could I be pregnant?

As you can see I am 11 days late. I am having cramps like my period is bout to start, gas, itching boobs, emotional, and just wanting weird stuff. I have token a test at 7days late (at night)and was bfn. Having to wait untill I go home to take a test again (hubby works on the road and I ride with him). Does anyone else have the same symptoms and was pregnant?! Help! Thanks in advance!!
