Waiting Game!!

Hello ladies. If pregnant I am 6 weeks and 3 days pregnant. I took a HPT test and the results were negative. But i know that I have to be pregnant. I have never missed a period in 4 years. Today I am 11 days late and feeling very pregnant. I have a hard-ish bloated tummy, increased appetite, cramps, gas, headaches, back aches, light headed, and a little nausea with no vomitting. But I don't know if these symptoms are all in my head just because I want this baby so badly! ): Someone else have to kind words to help reassure me?
