Unsuccessful abortion?

I had a medical abortion on Wednesday. I was 6 weeks and 6 days pregnant. I don't feel I have to justify my reasons for the abortion as I know in my mind that I did the right thing, and have no regrets. After reading all the horror stories on the Internet I prepared myself for the worst, preparing for huge amounts of pain and a lot of blood. I took the 4 pills orally at 2:50pm and hurried home, by 3:30pm I was in extreme pain, I just burst into tears and lay dead still hoping id fall asleep. By 4pm the pain subsided so I finally plucked up the courage to stand up and go to the toilet. Upon this I passed a large clot, at least 3-4 inches in length. After which I was completely fine the pain ceased and bleeding subsided about half an hour later I passed another 2 clots which were pretty small. And for the rest of the night I was fine. The next day I took the antibiotics given to me by the nurse and felt well enough in myself to return to college. The antibiotics were the worst they knocked me completely. I felt dizzy and sick and these I believed were worse than the day before I ended up being sent home at 9:30am due to being sat in the toilet the whole time. After four hours (I assume the antibiotics had worn off) I was fine and able to get on with things that needed doing. Today I feel mentally and physically fine, bleedingg is now very minimal to the point where I feel it may stop soon but my question is I'm concerned because of how easy (physically) it was has it been unsuccessful? I assumed bleeding would last for 2 weeks and didn't expect to pass the pregnancy less than an hour after taking the tablets. Any advice would be greatly appreciated.
