Is there any example of giving birth to a healthy baby when progesterone is as low as 0.3 in the early pregnancy?

Low progesterone does not mean that the baby is unhealthy, only that there is a risk of miscarriage. If low progesterone is found early, preventive measures should be taken. The doctor will arrange for you to be hospitalized for observation and miscarriage protection. Not very serious, you can take some vitamin E, and some take progesterone to prevent miscarriage. It is good to see a doctor in time for some symptoms during pregnancy. You all detected low progesterone. Assuming that the doctor will arrange a reasonable decision for you, everything will come naturally.
