Intuitions are quite tricky. We should not base our belief system on them. We believe in our path because we intellectually accepted it with proof and logic. This is the foundation. As for intuition, most people who follow other religions will claim that their intuition tells them they are on the right path. Hence, one should not give much importance to intuitions.
As for knowing that Allah has accepted your efforts, then as long as:
1- You tried your best to be sincere
2- You did not act arrogantly
3- You fully believe in Allah’s mercy
Then know that He has accepted your efforts.
