I burn and itch. Sometimes a lot sometimes mostly at night. From scratching so much i sometimes get small paper cuts like from all the irritation. It occasionally burns when I urinate or have sex. Every once in a while I get lower abdominal pains. I had unprotected sex 8 to 9 months ago. I also have an IUD(Mirena). Could this be a STD or just a yeast infection? Or can this be from my IUD? Need advice please!View Thread
