Your symptoms suggest that you have pelvic issues and there could be an infection in the pelvic organs, a cyst of the ovary, an erosion of the cervix
, polyps etc. The sudden onset goes more in favor of an infection and/or a cyst. Please see a specialist for a proper clinical appraisal of the situation. You would need a pelvic/trans-vaginal sonogram, blood counts and urinalysis
. Please avoid stress
, further intercourse until the symptoms heal and take sufficient rest. Hope this helps.
