The bleeding in the fifth week of pregnancy depends on the amount of bleeding, including the blood HCG value and the progesterone value, to determine whether it can be preserved. For example, if the bleeding in the fifth week of pregnancy is relatively small, only brown discharge, and the progesterone value is within the normal range, and the HCG value is also within the normal range, you can apply progesterone medication, such as intramuscular progesterone or oral progesterone, at this time, to keep the baby. For example, at five weeks of pregnancy, the bleeding is very heavy, similar to menstrual flow, and the progesterone level is plummeting, and the HCG is not doubling, suggesting the possibility of miscarriage. However, nothing is absolute, you can keep the pregnancy for a period of time, if there is a gestational sac expelled during the period, there will be the possibility of miscarriage, it will not be kept.
