so I’ve recently been sexually active and I’ve been itchy down there, discharge appears yellowish is that normal?did I get some kind of infection? Did having sex through my PH level off to cause this? I feel like peeing even feels different but I’m not sure if I’m just overthinking that. I just feel kinda irritated down there and like somethings off. It was my first time w no protection . what should I do? is there any at home remedies or over the counter things I could buy? Should I be getting checked and if so where?
