Spotting or period??

Myra

So I'm not sure what to feel about but... last week around Christmas day i thought my period had started but nothing was getting on my cortex and it lasted for like a day and a half maybe 2. My last period was Nov. 23rd and recently I had bought a test, 3 to be exact, and 2 came out negative. I just want to know when can I exactly take the test, I don't know if I'm doing it right or too early to take it.
