Disappointed...

so me and my boyfriend aren’t TTC but i missed a birth control pill two weeks ago and it’s the only form of contraception we use, as we don’t even use the pull out method. i noticed today that i missed the pill when i saw my old pack in my purse so i went to the store and bought a test just to be safe. it was negative, and i found myself a little disappointed...is that normal? now is definitely a terrible time for a child but i was honestly a little bummed to see it negative.
