Conservative treatment of ectopic pregnancy can be done with methotrexate intramuscularly or intravenously. The response to methotrexate in a few days is different for each person. There are some people who have failed conservative treatment with methotrexate and do not have a reaction. During the course of conservative treatment with methotrexate, you need to review the ultrasound to see if the ectopic pregnancy mass continues to increase in size. If the mass does not continue to increase in size, it is effective as long as the blood HCG drops. If the mass does not continue to grow, it is effective as long as the blood HCG drops. Under the conservative treatment with methotrexate, you need to be hospitalized in bed for rest and observation to avoid bleeding due to the rupture of the mass caused by strenuous exercise, and review the blood HCG and ultrasound in a week.
