I am due for my period tomorrow or even late tonight. I've been having a lot of discharge, I don't know if this is normal. I have had itching, which is what had drawn my attention to the discharge. I took a yeast infection test and it was negative. But, if I have one, is it normal before periods? I read online that it could be due to hormonal changes before periods. But, I don't have a chance of being pregnant, it said it can also be early pregnancy, but I haven't had any symptoms. Is it normal before a period?
