If the completion of abortion
was confirmed earlier through a follow up sonogram, then this is another pregnancy
which may have terminated in an abortion or is threatened. The only way you can know is through a sonogram, preferably trans-vaginal. You can also couple it with serial serum beta-hCG
assays as doubling titres every 2-3 days indicate good status of the pregnancy. Please see a specialist for a complete evaluation and proper guidance. Hope you find this information useful. Wish you good health.
