TMI ! TMI ! Yeast or BV?! 24 weeks pregnant

I just woke up this morning with a very irritated and itchy vagina! On the outside! Some discharge is coming out, not really a smell. But my lips and clitoris are so ITCHY! Idk why I sleep with no panties to let it breathe 😞 but this has happened. Should I call my doctor or what should I do!?
