Hello dear Understand your concern First you have to find the cause of miscarriage likethyroid disorder, diabetes, genetic problem in one or both partner, antiphospholipid antibody syndrome and other autoimmune disorder. HCG 5000 injection is given in high risk pregnancy (history of miscarriage) to prevent the miscarriage. It support the pregnancy and does not affect the baby. It should be given till the 10th week of pregnancy to prevent again the miscarriage. Lonopin is generally given in the antiphospholipid antibody syndrome or autoimmune vascular disease. It given IN APLA syndrome to maintain the blood supply once cardiac activity found in the USG scan. It does not affect the baby in APLA syndrome case. So first clear the your cause of miscarriage and then take proper treatment. You can also use aspirin.
