Reverse abortion first pill. Thoughts.

Hi I am 7 week pregnant. It was a healthy pregnancy but as I And my husband was unsure about pregnancy we thought of removing it and told our doctor for abortion. She asked me to pop a pill which I popped around 5:00 pm today and she called us tomorrow fr rest 4 pills to continue with abortion process. However I was really sad and when we came back my husband seem to b repenting on our decision. We thought if we can reverse the medication taken and continue keeping the kid but this looked scary cz i already got one small /light spot of blood and also wat all effect the first medicine must have done on pregnancy progress and on fetuz and how safe and sound kid b inside if we continue the pregnancy as the development stops immediately after taking first pill. Can someone pls help and suggest and guide. On my thoughts.
