Please help me with my negative tests

[Amywoodley]

I get regular periods every month usualy towards the end of the month.. last two periods i had, came really early.. its now been 5weeks since i had my period. ive done 2tests now and both say negative.. havent had many signs apart from pains in my stomach, sore breasts, tiredness, and strange eating habbits and my stomach feels tight.

i dont know weather to wait a little longer to be sure, then go to doctors? could the test be wrong or am i just not pregnant.. i have been trying for a while.

any answers? x
