Hi welcome to H.C.M.Forum. according to your symptoms it appears to u.t.i, if you are pregnant long back you wont be so calm so long. infection starts & there will be concerned symptoms.
what ever the reason may be you have to under go D&C. then use medicines for infection. antiverted uterus may be commen oterwise also. ovarian cyst can be confirmed by u.s.scaning only. but the attending doctors examination have its own value. she is the better judge. wishing an early recovery.

hi, you have not mentioned your last menstrual period date. Pain with overdue period with spotting is at times present in ectopic pregnancy,which also will reveal weakly positive urine pregnancy test and doppler ultasound will reveal increased blood flow. If your urine test is negative for pregnancy then to reconfirm either undergo ultrasound or Beta hCG in blood.
Certain pelvic inflammatory conditions of the pelvis like pelvic inflammatory disease also produce pelvic pain. If you have doubts about endometriosis, the the pain of endometriosis preceeds your due date of menses. You can confirm it on ultrasound wher large choclate cyst are seen radilogically.
So do reconfirm again by urine pregnancy examination-if negative then by ultrasound.Thanks..
