I have been having pain in my uterine/ovary area in my pelvis for about four months. Recently I have been getting pain also in my lower back and upper thighs, as well as cramps that feel like period cramps but are relatively constant. I have also had very very occasional intermenstrual bleeding (two occasions of bloody discharge and then some blood on a tissue after sex), but no unusual discharge, no burning or irritation when I pee although sometimes it feels difficult to urinate but without pain. I am so confused as I am not pregnant and I am I pretty sure I don't have an STI, as I have only been with one partner in the last year who has tested negative. I am waiting on a chlamydia test and am hoping for a cervical examination. Just very worried this could be some form of cancer or that I am infertile at this point as the pain is almost constant now.
