If you experience stomach pain and blood in the early stages of pregnancy, you should go to the hospital promptly for examination. One of the common causes is pre-eclampsia and the other is ectopic pregnancy. If there is a preterm miscarriage, timely examination should be conducted to determine for birth control, and if it is an ectopic pregnancy, symptomatic treatment measures need to be taken in a timely manner. In case of early ectopic pregnancy, conservative treatment can be taken by taking the drugs mifepristone and misoprostol to avoid serious development of the condition. First of all, the progesterone value should be determined. If the progesterone value is low in intrauterine pregnancy, oral progesterone or intramuscular progesterone injection can be administered to preserve the pregnancy.
