Nausea and headaches/ too soon????

Okay so for the past week I have been randomly nauseous and tired. Headaches out of nowhere....my period is in 4 days do u think n its to soon to test? I know I should just wait to see if I Jane one or not but I admit I'm impatient. Plus i just really want this so so bad. Fingers crossed! I cried at my last test when it said no. So maybe I should wait..... hmmm... help!
