Vaginal Discharge

So I have irregular periods. Usually 8 days and super heavy. My last one at the beginning of November was 6 days long and noticeably lighter. I have a discharge sometimes but not like I have been here recently. It looks like lotion and is the color of white toothpaste. Its been appearing for the past few days. And I have been bloated all day everyday for the past three weeks. Im supposed to start my period on the third of this month. I always cramp on the first and last day but never a few days before. Can someone help me out?
