Do you think I should use zero conditional of first conditional ?

Answer

You forgot the verb after "will": If there is no problem, there will be no need to worry.

The conditional you use depends on the rest of the paragraph.

Answer

Both are equally correct.

The one you use would depend on whether the other person is likely to worry at the moment or at some later point.
