How long has it been that your late? Do you have any stress in your life right now? Your safe bet is to go to the doctors and see you don't need to tell anyone about going they don't tell anyone too

Most women don't get a reliable result on an at home pregnancy test until after the first month. Wait until your next period is due. If you miss it, test again. Make sure to use first morning urine, or see your doctor for a blood test.
