Just need someone else's thoughts on this

So AF was due 4/29 it is now 4/30 and she hasn't shown up I took a test 4/29 but it was negative I used clear blue digital with the weeks counter btw also AF the last 2 or 3 months always showed up 2 days early could I still be pregnant even though I had a negative test or am I just over thinking and reading into things? I'm hoping to get a positive before I drop my husband off to the airport on 5/2 because he going to boot camp for 10 weeks he's had a rough last week and this would be a nice good thing for him before he leaves!
