Whether or not the baby can be kept without medication in clinical cases with low progesterone depends on the specific situation. If the low progesterone is caused by pathological factors, such as luteal insufficiency, abnormal thyroid function or poor tolerance of the uterine cavity, the low progesterone in this case needs to be preserved. If you don’t keep the fetus in time and don’t get rid of the factors that cause the embryo to develop poorly, you are likely to have a miscarriage and the embryo will stop developing. If low progesterone is a physiological, that is to say, an individual difference resulting in low progesterone, the normal range of progesterone after pregnancy contains only 80-90% of women, and some women have no abnormal embryonic development after pregnancy, however, the level is relatively low and does not require birth control, the child itself is developing very well.
