I some time feel movement in my stomach. Am always tired, tirsty, craving food. I don't want to buy a hpt cause I don't want to go through the ffact that I am not pregnant because I really want to be.

Buy a test. If you think you feel movement, you are kidding yourself. No matter how badly you want to be pregnant, you can't possibly feel movement at this stage. If you had a period at the normal time, even if it was light, you are probably not pregnant, but you need a test to be sure.
