A drop in progesterone at 5 weeks of pregnancy is caused by luteal insufficiency and needs to be treated with progesterone supplementation given under the supervision of a doctor.
Progesterone is an important hormone for maintaining a normal pregnancy and is mainly secreted from the ovarian corpus luteum up to 6 weeks of pregnancy. When the corpus luteum is not functioning adequately, it can lead to low progesterone. Therefore, low progesterone at 5 weeks of pregnancy is also caused by luteal insufficiency. As it can increase the risk of miscarriage, it is necessary to give progesterone or dextroprogesterone and other medications under the guidance of the doctor to supplement progesterone to protect the fetus.
Early pregnancy should also pay attention to rest, continue to follow the doctor’s instructions to take folic acid on time, prohibit sexual intercourse, after treatment and review of progesterone value is normal, and ultrasound suggests that the embryo is well developed can continue to be pregnant, but if there is an increase in vaginal bleeding or abdominal pain aggravated by the value of progesterone does not rise or fall, more suggests that the miscarriage is inevitable, need to terminate the pregnancy in a timely manner.
