Ughhh

Recently just went to the gynecologist and they said I had bacterial vaginosis which I think is the same as a yeast Infection down there but I took at 2 day pill they prescribed for me & i don’t think it really worked. I have been itching crazy!! I scratched to the point where it hurts to touch it and when I wear pants/panties it rubs on right above where my clit is and it hurts so bad because the skin is open from me scratching( it’s like a paper cut). But i can’t go 2 minutes without scratching(not exaggerating at all) Does anyone have any idea why I’m soooo itchy??? Or anything that they use to help ??

Idk if this is relevant but I’m 17 & just had a daughter 8 months ago
