Hi, I’m Kayleigh and I had sex a few days

Patient: Hi, I’m Kayleigh and I had sex a few days ago, since then, when I pee it burns. My uterus hurts a little, I feel like I have to pee all the time, my lower back hurts and I have been getting uncomfortable laying on my bed. I am also on an implant birth control in my arm. I dont know what to do, could you help me?
