Confused vagina

Hi guys, so last month I had two periods due to taking plan bs (that’s never happened before but oh well) and no, based on Eves calculations I’m 3 days late BUT lately I keep getting this EXCESSIVE white discharge, no smell but there is soooooo much. To the point it drips into the toilet and runs down my thighsz I’m really confused and want to know if anybody has a clue? No smell, this has happened before ( the last couple weeks), but today the inside of my vagina hurts like a yeast infection or friction burn so that’s new.
