I'm only 16 and never had sex but my period is 3 months late (haven't gotten it in 111 days to be exact). I told my mom a few days ago and she said it should be okay and she used to be a nurse but I don't know... I'm just kinda nervous something is wrong with my body. I got my period in 7th grade, so it shouldn't be irregular by now since it's been over 3 years. Should I be worried? See my doctor (never been to OBGYN)? Wait it out? Any advice would help :)
