Hallow Dear, Progesterone is a hormone required for stabilizing the pregnancy. This hormone is prepared in large amounts by placental tissue or the precursors of placental tissue. Before placenta is formed, it is the chorionic tissue which produces hormone hCG in large quantities to support the other progesterone producing tissues to produce progesterone. Hence, if there any signs suggesting that the pregnancy is at risk, particularly early pregnancy, either hCG or Progesterone or both are given to stabilize the pregnancy. The signs demanding for these are mainly bleeding in the first three months without pain in the abdomen. Sometimes, if there is bad obstetrics history with previous abortions in first three months, these medicines are given as a precaution. If you do not have any such history of symptoms, you may not require Injection of hCG and/or Progesterone. However, please continue to take Folic acid which is very vital for the growth of the baby. I hope now you can take an informed decision. Dr. Nishikant Shrotri
