I am 29 years old and had a miscarriage 2 months ago. My indirect Coombs test is positive. My blood group is B negative, and my husband blood group is A positive. My TORCH test results are: Toxoplasma IgG: 44 Rubella IgG: 25 Cytomegalovirus IgG: 32 All IgM tests are normal, including HSV. My lupus anticoagulant test shows a borderline value. My doctor has prescribed R vaccine, Acivir, and Rovamycin Forte. Is it safe to take these medications? My doctor did not explain the cause of my miscarriage, and I am concerned about the treatment.
