What does it mean when there is bleeding with uterine contractions?

Bleeding due to uterine contractions is generally caused by relatively low progesterone levels. Progesterone can be supplemented by taking oral micronized progesterone or dydrogesterone tablets to help stabilize embryo implantation. If the bleeding is caused by other reasons, the patient should undergo a color Doppler ultrasound examination. It is recommended that the patient maintain a regular sleep schedule and avoid consuming spicy or irritating foods.
