When should I take the test?

Missy
Quick question for you all. My last period was Nov 21-29 and I've been waiting for it to come for awhile now. My husband and I had sex on Dec 28 or 29th and I just want to know when should I take a pregnancy test?? I just used a clear blue and it said negative so I'm thinking it may be too early. 
Thanks in advance 😊
