late period, but negative digital test help

Whitney
First time I've had to try to concieve and I'm so frustrated! (This will be baby #4) today I was supposed to stayer... but AF is a no show. About 3 pm I took a left over (unused) clear blue digital and it said "not pregnant" so bummed... should I test again? With my last pregnancy I tested negative until 5 days later where I went to the dr thinking I had a mass in my uterus and wasn't starting for that reason... but nope it was #3 (my son) 
Hell, I don't want to get my hopes up... but I'm praying this means I'm pregnant!
