How Should Period Pains With Less Bleeding And Follicular Problems Be Treated?

Hi! I am 31 years old. Married from last 3 years. Planning family from 9 months. Is Suffering from severe pain in periods. My Normal menstruation cycle 32 -35 days bleeding happens only for 2 days. Jan cycle lasted 40 days and Feb was normal 32 days and march again was 45 days, HTP negative.
I consulted Gyn and she advised many tests - suspected endometriosis. FSH, LH,TSH normal ESR high(65), Monteux negative, TB Elisa IGM negative, IGG negative, IGA borderline positive(588). Currently going for a follicle study today is day 20th (25mm) follicle size has not ruptured. Please advise what should I do? What is TB PCR test and LFS?
