I am on the same boat with you. Last period was Aug. 3rd and no period yet....mild cramping sore breasts and negative test....hope someone had the same thing and answer us :)
you should go to the hospital and get a blood test, you need to find out cuz if you are pregnant,you got to see an obgyn asap!
I have an irregular period so when i didn't get my period the next month i did not worry too much. I then started with tender breast so i took a test and it was negative. My symptoms worstened i had nausea, fatigue ect.about 3 weeks later i went to the docs and the test was negative. 2 weeks later i went for the results and they had me do another test it was positive. I have officially known for a week but i think i am really over 2 months.
