I'm a little worried, my period is late by a week, so i went a month without getting it. My cycle is usaully irregular, I can never keep track of it, sometimes its a bit early most of the time its a few days late. I have been about a week late before but I've recently lost my virginity. I used a condom and he didnt finish inside me so I know my chances of being pregnant are slim but I guess I just need re urence. I have been under a lot of stress lately and I know worrying wont help. I would just like to get some feedback from someone who would know more about this than me.
