Cleaning thoroughly in istinja

Q: I passed stool and made istinja and I checked with tissue there was no impurity then i did wudhu and I felt there is some impurity but I did not clean it as I was not sure about it. I offered namaz in this condition and after namaaz I checked so there was impurity. Then I cleaned it off and I did wudhu and offered namaaz again. Now I am very worried that as I had offered naamaz with impurity so my Imaan lasts or not? Do I have to do ghusal? I recited Kalima shareef and made tauba but still I am so worried. Please guide.
