IS THIS A YEAST INFECTION?7

Hello, my discharge has been consistently like this for the past year or so. Sometimes it itches (like today) but most days I'm fine. I have no idea if this is a yeast infection or not. This is the max discharge that ive seen (its been this much before). For maybe 5 days out of the month i gave no discharge but most of the time its this consistency. I've taken numerous yeast medications and im on a daily probiotic (renewlife 25billion) I just don't know anymore. Pic of my panties after wearing them all day for reference as well.
