Thanks for the query.
You didn't mention you age parity.
You better consult gynecologist, go for physical examination and speculum examination to rule out pelvic inflammatory disease
and any possibility of pelvic organ prolapse.
You once go for urine microscopy and if need culture and sensitivity.
may also be needed.
With this workup the possible cause for your problem can be identified and treatment can be given accordingly.
