###Human: Until how many weeks into the pregnancy is abortion possible? ###Assistant: Hello. The medical or chemical termination of pregnancy is safe and effective until 10 weeks. If it is beyond 12 weeks, surgical procedures may be required. If you take an emergency contraceptive pill within 72 hours of intercourse, there is no chance of a pregnancy. They are safe and effective. However, if you have a doubt then get back to me. Take care. For more information consult an obstetrician and gynaecologist online -->
