So my last period was on Septmeber 11. I have very very light spotting on October 11th, but no period. I've take 3 pregnancy tests and all came out negative, so I went to the doctor. He said I wasn't pregnant. Where's my period then? I'm having some symptoms (nausea, missed period, sore breasts, dizziness, sleepiness, bloating/weight gain, cramps). I don't know whether it was too early to tell if I am pregnant. What do you think...

Well it depends on the date you had sex. But I honestly think that it is just stress.
