Am I pregnant????

Okay I know what your thinking I know I shouldn’t have been having sex I was just curious and I am a A honor roll student I’m a good child I was just curious... but my period is really irregular it always has been it stays off for like months and then stays on for a month or so but It’s off right now and I have been having like cramps in my stomach but no bleeding I’m scared to buy a test because I’m afraid my mom or dad will find out they will totally kill me
