Hi, Fluid in the pouch of douglas indicates you are having PID (pelvic inflammatory disease). Treatment requires anti-biotics and antiinflammatory drugs like ibuprofen in certain cases. You can go for a swab culture sensitivity and have the antibiotics accordingly. An anti-fungal vaginal tampoon would also be helpful. Maintain proper hygiene, Taking your husband to your physician for an examination might also prove beneficial,he may also require a course of antibiotics. As soon as your infection is treated and everything returns to normal,you can concieve with proper family planning. Take care
