There can be many different reasons behind your symptoms. To more accurately identify the cause would require a much more detailed medical history, physical examination as well as the tests that you have done.
Some of the possible causes for your symptoms may include:
- Pregnancy
-Lower genital tract infection including sexually transmitted infection such as chlamydia
-Cervical pathology
-Endocervical or endometrial polyps
-Hormonal related problems
It would be difficult for me to comment on what tests your doctor has already done for you and whether your symptoms have been adequately investigated.
However, if you are still concerned regarding your persistent symptoms, it may be a good idea to seek a second opinion with someone more experienced in treating female health related problems.
