I was not sure whether I am pregnant or not?

I am a 22 year old girl who has had an unplanned pregnancy. have gone the way of an abortion. I was not sure whether I am pregnant or not because I did not take a pregnancy test. No pregnancy test but I did do abortion kit, called Mifegest kit, on the third week. On day 2, I had heavy bleeding and I saw some kind of ejection of meat or flesh looking material. I wanted to make sure that whether I was pregnant or not. It has been a week after taking the abortion pills, I am still having bleeding. Did I do something wrong….what should I do next?
