I just got a job as a lifeguard. I've only used tampons once and that was almost a year ago. I work this friday and I'm supposed to get my period any day now. My mom only buys the regular size of Tampax Pearl. And that's fine because I used them last time. But, how long do they take to be all soaked up? I work 1:00 to 5:30, but have a break at 2:00 and 5:00. I can call the front desk if I need to go to the bathroom. Will I need to change it before three hours? I won't have a pad on obviously, but I'll be on dryland. Will it leak?
Thanks,
