Missing my birth control

Idk why but for 2 weeks now I keep missing taking my birth control on the right time. It’ll be either 20 mins - hour late and it’s really annoying. I’m taking oral birth control til I head to boot camp or until I stop being scared of getting a Iud or something.

This is the first time I’ve started birth control and I was wondering did anyone mess up like I did? I’m going try get it on time tomorrow night it’s just so annoying
