Feeling pregnant but tested negative.

Hi, I am 2days late on my period. I felt heartburn, cramps, lower back pain , and tingling tender sensation on my breast and exhausted every noon. I am moody for the past few days too. I wasn't able to visit clinic earlier cause they don't have obgyn that time. I tested at 11am earlier after I got home and I got negative. Should I wait for 1-2 weeks before I should take?#pregnancy #1stimemom #advicepls #pleasehelp
