I am deeply sorry for your loss. Please be reassured that positive IgG results for Rubella and Cytomegalovirus (CMV) typically indicate past exposure or immunity, not an active infection. Therefore, they are highly unlikely to be the cause of your miscarriage. Regarding your medications, famciclovir (an antiviral) and spiramycin (an antibiotic) help manage or prevent specific viral and bacterial risks, while nutritional supplements support your body's recovery and future reproductive health. It is always best to discuss these results and your recovery plan with your gynecologist for personalized guidance.
