Pregnant or just late?

I've been SUPER cranky and absolutely exhausted the last week. I'm talking falling asleep during my lunch break, at 8 when I sit down on the couch, and going to bed by 10 because I can't keep my eyes open. AF was due Wednesday and is nowhere in sight(not even drops). It's usually only a day late if that. Ive also been super nauseous any time I eat. My husband and I made a deal that I would give AF a week to come through before testing so I need opinions! I have been the usual pmsy too though. But I strangely have not had a SINGLE cramp and I usually cramp extremely bad the day before its gonna start. Start sending the baby dust ladies!!
