Itchy!

Hey ladies, so kinda tmi, but isn't everything on here?! Been kinda itchy downstairs last night and today. When I'm distracted I don't feel it at all, but as I'm sitting still it's pretty annoying! I put some lavender oil down there this morning, because it's antifungal and antibacterial without being harmful, and I felt super warm, but it stopped itching! I stay clean, haven't had unprotected sex lately, and my partner does not have an STD or STI. I dont know if it makes a difference but I am in my fertile window, and my vaginal fluids have smelled more musky than usual. Not bad in any way, if anything better! Just don't know what could be going on and Lord knows if I ask my mom she'll throw me in a doctors chair so fast my head will spin. Any ideas would be helpful! Thank you!
