your symptoms are going more in favour of pelvic inflammatory disease
it can be bacterial in origin.
your upper abdominal pain
may be due to the gastritis
or can be a disease known as gastro esophageal reflux disease
your symptoms are vague and it can be confirmed to doing blood tests and ultrasounds to rule out the same.
i would advise you to consult a gynaecologist and a gastroenterologist for the obove complaints
i hope i have answered your question
