Fluid in posterior cul de sec. Tested?

I have been going through fertility treatments about a year My period cycle is normal every month No issues in period as well Doctors have to say it is pcod and ovary producing many follicles Lately I got acne in armpit and near lower abdomen area and a dermatologist prescribed me Rcin 450 with other medicines but didn't indicate anything related to tuberculosis The regular gynac doctor while performing routine sonography this week spotted there is excess fluid in posterior cul de sec which wasn't present earlier before Gynac has to say this might be tuberculosis What are my various options? I never had coughing or any other tb symptoms Should I go through laparoscopy as suggested by the gynac to extract fluid and get it tested? Or what are other options without any invasive procedures
