Hello there
No the grammar there is not right, you should not use past tense.
You should say "There's no need to worry" or "don't worry about it" or "don't worry too much"
Something similar to what you have said there is "no worries", but it is only used when, for example, someone has helped you and you said "thank you", then the other person may say "no worries", meaning 不用記在心上.
Hops that helps =)
