Monistat 3

Wondering if anyone has used it before? I woke up to irritation (itching and inflammation) down there two days ago. I’ve used Monistat 3 and I’m on my third day now. Yesterday when I wiped the cream was white and today I’ve noticed a light/green light yellow mixed in with the cream. Is this normal? I’ve never had a yeast infection before. I have an appt with my primary Dr Thursday just to follow up and be safe but what the hell, this hurts and is so itchy!
