Is It Possible That My Abortion Was Unsuccessful If I M Experiencing New Symptoms I Didn T Have Before The Procedure?

I did abortion 7 days ago through d&c but before the abortion there was no symptoms relating to pregnant, the only reason why I did test and notice that I was pregnant was because of my missed period which I run test and tested positive so I have to do abortion but since I finished the abortion I started having different kinds of unpleasant feelings and experience which I never had before the abortion. Please does it signifies that the abortion wasn t successful that I am still pregnant.
