Why doctor suggest HCG injection during pregnancy?

HCG injections are not typically a standard treatment for a normal, ongoing pregnancy. They have specific uses, primarily in fertility treatments to induce ovulation. In certain situations, such as in some cases of recurrent pregnancy loss, HCG injections might be considered to support the function of the corpus luteum, which produces progesterone. However, this is a specialized treatment initiated and closely monitored by a fertility or high-risk pregnancy specialist based on a thorough evaluation.
