I have the same thing white discharge (no smell), back pains, and i feel a little of nausea , but I dont remember my last period and I have not gotten my period Oct month and I took a hpt and it came out negative. Could the discharge be that your ovulating ??
Im not worried about my period since I have a irregular period.
does the discharge smell? If it is only a light smell or odourless it is nothing to worry about and could be a sign of pregnancy .. if there is a bad smell it could be an infection. Have you done an hpt? that would be the only definite way of knowing if your pregnant - or getting a blood test from your doctor.
