Cramps

I’ve had cramps everyday for the past two months, along with almost constant nausea and lack of energy. I know I’m not pregnant as I got an IUD in March, and I’ve taken multiple pregnant tests and was tested at the hospital 2 weeks ago. I know my mom had ovarian cysts at 15 and ovarian cancer at my age, 18. I’m not sure what to do. Go to my OBGYN obviously, but I’m a college student and don’t get a chance to go until mid December. Do I need to be worried?
