Hello, Medical abortion is the best choice to terminate 4 weeks pregnancy. You need one Trans Vaginal ultrasound to know the nature of conception (tubal/ uterine) before taking abortion pill. However, self administration of abortion pill is NOT recommended. You don t go for that though it is illegal in your country. The abortion procedure is associated with several risks and complications like nausea, vomiting, abdominal cramp, excessive vaginal bleeding, fainting etc. You can t control them by yourself at home without doctor s help. This process can be done at home if you consult once with LOCAL DOCTOR as you have to go for follow up examination after 2 weeks to confirm that abortion process is completed. One pelvic ultrasound scan may be required to check retained bits. Around 5% women may need D & C or suction (surgical method) to evacuate the uterine cavity. Good luck.
