For pregnant women, if progesterone is greater than 25ng/ml, it is normal, and if it is less than 25ng/ml, it means that progesterone is reduced and there is a risk of preterm abortion. It is necessary to choose whether to use progesterone drugs for treatment according to the patient’s specific condition and under the guidance of a professional doctor. It is also necessary to pay attention to rest, not to carry out strenuous activities, not to overwork, not to stay up late, to avoid mental and psychological stimulation in all aspects, to reduce work stress, and to pay attention to a nutritious diet, which is conducive to improving the disease. When progesterone is lower than 8ng/ml, the possibility of ectopic pregnancy cannot be ruled out and timely diagnosis and treatment is needed.
