Hi Thank you for asking HCM. I have gone through your query. Fish oil doesn t give such problem . It can be due to infection. Bacterial vaginosis gives characteristic fishy smell. A swab test should be done to rule out the condition. For bacterial vaginosis I treat my patients with metronidazole or clindamycin with clotrimazole as vaginal suppository or as oral tablets. Using intimate wash regularly will be helpful to normalize vaginal bacterial flora and PH and prevent such infections. Fibroids can get infected. In case of that there will be associated pelvic pain and bleeding. Ultrasound examination can be done to rule out that also. Hope this may help you. Let me know if anything not clear.
