I'm a 20-year-old female and have had my period since I was 11. It's normally very regular, starting about two days later than the last mont [for example june 10, and then again on july 11 or 12.]

my period is now over two weeks late, and i'm growing concerned. I have never had a lapse in my period. I know it isn't pregnancy because i've never had sex.

Now I know there are some serious menstrual problems in my family [my mother takes a perscription for severe bleeding and endometriosis, and my grandmother had to have a hystorectomy for similar problems,] but my sister's problems are much different [unless she takes birth control regularly she goes months without her period, and when she gets it again it lasts months.]

i haven't experienced any symptoms, and it's the first time my period has been late, but because of the issues in my family i'm growing concerned. I have a yearly physical coming up at the end of november, but I don't know if I should wait until then or not.
