Preggo?

Lauren • You get what you give.
My husband and I have been trying and decided to quit trying for a little while if I didn't get pregnant this month because of some time issues with him being gone while I would be pregnant.
My period was due yesterday and still no sign of AF. The only things that could be signs of AF or pregnancy are that my boobs hurt and are more full (this happens even when I'm on my period) and I'm insanely fatigued (even after an hour long nap and 6 hours of sleep last night). I've almost fallen asleep sitting up at my desk 3 separate times today. 
I took a test 3-4 days ago (test box said it would still be >99% accurate for my dpo and it was negative...should I test again or just wait it out? I've hated going out and buying a test just to have your period the next day or something.
