Okay so!!!

Melisa • Name is Ashley. 23 Years young. Married.
My period was due on 9.24.15. And I am 6 days past due as of today, I took a pregnancy test before I was supposed to start my period and it was negative, and I took one yesterday I was 5 days late yesterday. Both tests were the cheap dollar tests. My husband and I haven't had sex since my last day of being fertile which was two weeks before the 24th the day I was supposed to start my period. Today being 6 days late and after two negative pregnancy tests I'm now having a milky white discharge and some upset stomach. And I've been having acne flare ups which isn't normal for me. I'm not stressing myself over it because I know you can trick your body into thinking you are. Can any of you tell me what this means or if I should test again? Need advice!!!!
