Should I test? HELP!

Tamara • 20 white female. Ttc #2
So I had my period November 14 from the start of yesterday my boobs have been very sore and I have been feeling sick to my stomach I am trying for number 2 I'm just so sick of getting a BFN I'm scared to test glow says I shouldn't be ovulating till the 5 but my cycle is so out of control I don't know if I should trust it I didn't get my cycle in October at this point I get my cycle about every other month  I already went to the doctor no sign of cysts or any complications I'm so confused
