Trouble?

Last week on Thursday, I found out my twins hearts had stopped beating at 8 weeks, that same day they gave me misoprostol, I took it that night and was the worst pain I have ever been through, I am 18 years old, and this was my first pregnancy, after reading up on the medicine it says it should last up to 12 hours, but tomorrow makes a week and I am still bleeding and in a lot of pain. I don’t want to eat, it hurts to get up and down, and to walk. Is this normal? Should I contact my doctor? Please no harsh comments, I’m just at a loss of what to do, and currently don’t have the money to go see the doctor, and just would like some feedback..
