Early sign still negative

So i was on bc from the first day of my supposed period but that was way longer and lighter then it usually is ( the week before there was one time he came in me. That was in August. Come October I left him due to him being violent against me and my son to the point I was scared. Now it’s November and I still have not had my period back since possibly that one in August. I have taken 4 urine tests 2 faint positives and two negatives. And one negative blood test. I’m nauseous as can be, extremely tired, cravings, all sorts of smells bother me now. White stringy discharge, I have loose stool and now I have slight cramping i have been to the doctor twice now. So now I’m wondering if I could be and there was a fluke or something with the test since the symptoms have not stoped.
