A little bleeding in a new pregnancy is a sign of preterm miscarriage and needs to be treated with oral medication for fetal preservation. You can take progesterone capsule 50mg orally, 2 times a day, and dydrogesterone tablet 10mg, 2 times a day, plus vitamin E soft capsule, 1 capsule a day. During the period of fetal preservation, you should pay attention to rest, refrain from strenuous activities, prohibit sexual intercourse, do not eat spicy and stimulating food and cold food, eat more green leafy vegetables and fruits, and keep bowel movements smooth. Continue to take folic acid until the third month of pregnancy. If the bleeding increases and abdominal pain occurs, you need to consult a doctor in time. If the bleeding decreases or disappears after birth control, the pregnancy can be continued and regular maternity checkups will be done at a later stage to clarify whether the fetus is alive or not.
