Laparoscopy. Doctor help me with this?

My age is 25 years, I am single and sexually inactive. I am having persistent right sided pelvic pain since 3 months. Visited multiple doctors, done various tests and scans. But the issue has remained undiagnosed. Few months before this pain started and also now I get intermenstrual blood tinged discharge. But this discharge stopped when I took hormonal pills given by doctor. After completing course of pills, the issue of blood tinged discharge started again. The pain hasn't reduced, infact it gets very severe at a times. Although the pain is constant,but it gets way more extreme during periods. My gynaecologist had suggested for diagnostic laparoscopy and hysteroscopy. But she said it is to be done on 4th/5th/6th day of period. My Lmp was 7th Oct. As my pain is persistent and getting severe, I want this issue to be diagnosed ASAP. What should I do? Should I wait till next period or consult other gynae laparoscopy expert? I stay in Navi Mumbai area. Can any doctor help me with this?
