You can’t have a medication abortion when you are 31 days pregnant and have not been able to diagnose intrauterine pregnancy. Medication abortion, also known as medication abortion, is the termination of early pregnancy through oral administration of Mifepristone tablets and Misoprostol medication. Generally within 49 days of pregnancy can do medication abortion, but need to do ultrasound to confirm the diagnosis of intrauterine pregnancy before you can do medication abortion. At 31 days of pregnancy, the pregnancy is still relatively early, and it is possible that the gestational sac is not yet visible on ultrasound. You can do ultrasound to diagnose intrauterine pregnancy within 42-49 days of pregnancy before doing medication abortion. In addition, the pregnancy time is too short, the embryo development is not perfect. At this time, the drug abortion is easy to lead to incomplete abortion. Don’t be nervous, pay attention to rest, and go to the obstetrics and gynecology department of the hospital in time if you feel unwell.
