After pregnancy, you can take oral drospirenone tablets. The main component of drospirenone tablets is progesterone, a progestin that is closer to natural progesterone. For women with habitual miscarriages due to luteal insufficiency after pregnancy, they can be treated with drospirenone tablets until the normal progesterone level rises and the placenta attaches normally, then the drug can be discontinued. For patients with pre-eclampsia due to preterm miscarriage and contractions, you can choose dydrogesterone. Since dydrogesterone is a progestin close to natural progesterone, it can reduce the sensitivity of the smooth muscle of the uterus and be used to relieve the contractions of the uterus caused by hypersensitivity of the uterus, and patients should pay attention to rest and cooperate with drugs to suppress contractions, so as to achieve the effect of fetal preservation.
