It is possible. The only way to know for sure who the father is, if that is your question, is DNA testing.

Conception date is a best guess. There's absolutely no way to pinpoint exactly when you conceived.

If this is a question of paternity, the only answer is a DNA test.

I agree with the others... if the question is who the father is... you need a DNA test. There is no other way to be certain.
