Can Misoprostol Be Taken To Terminate Pregnancy?

Hello there, I am a desperate 21 year old lady who is 18 weeks pregnant and I found out 4 weeks ago that I was pregnant. This came as an utter shock to me because my body was not exhibiting ANY signs of pregnancy at all.No morning sickness no headaches no fatigue nothing.I just brushed off my missed periods as amenorrhea because I usually have that.The only sign I have until now is just some occasional bloating and the abdominal pain happened twice and stopped. I called up the man responsible and he blocked off any communication. My country has strict laws and the abortion costs are very expensive so can I use misoprostol myself at home and terminate this pregnancy alone without me dying? What are my chances of safe termination
