Progesterone and birth control pills can be taken together orally. Pre-eclampsia, or even miscarriage, mostly occurs in the first trimester, and the most common factor is low progesterone, so the main measure to treat pre-eclampsia is progesterone supplementation. In addition, we can also add Chinese herbal medicine to calm and fix the fetus, such as birth control pills. In clinical practice, the treatment of pre-eclampsia is a combination of traditional Chinese medicine and western medicine, that is, progesterone and birth control pills can be taken together. If the level of progesterone is too low, you can inject progesterone intramuscularly, if the level is not particularly low, oral progesterone can be corrected, at this time, you can also take progesterone pills orally to suppress contractions and protect the fetus.
