Could I be pregnant? (really need opinions!)?

i would be 5 weeks tomorrow, i guess (counting from the first day of my last period). i am 14dpo today. i took a test at 11dpo (not an early detection test) and got the faintest line imaginable after about 9 minutes. (it was a $1 test). well, i have been having LIGHT menstrual cramping the past week, and the last few days, some pinching feelings, which is something i have never felt before. i have started to get those "i could puke any second" rushes, am EXHAUSTED, and my have never been more sensitive. my husband swears my have grown a bit. and minor annoying headaches that i never get. what do you guys think? i am going to test again , i just really would like opinions. :)
