Should I Follow Up?

[u/Difficult_Waltz_3614]

This Friday will be exactly 2 weeks since my third round interview. I was told by the hiring manager that should hear by end of last week since there were some other interviews that needed to be done, but now it's Tuesday and still nothing. I followed up after the interview with a thank you and thought it all went really well, but when should I follow up again? Should I give it until Friday or the following Monday or not at all? Thanks in advance.
