Hi. I'm 19 years old. I had a regular menstrual cycle from my first menstruation until last July 11. I was expecting to have my menstruation around August 8-10 but I had it on August 26. I had protected sex last August 3. I took 2 pregnancy test 2 weeks after sex. Both were negative. I had my next period on September 30. I then felt a little relieved because it was only late for a week. Then I had my next menstruation on October 19. I was 2 weeks early. Now it's November 30 but I still haven't had my period. I don't feel any signs of pregnancy. I haven't bought another home pregnancy test because I'm too shy. I can't go to the doctor because my parents don't know about this. I can't tell them.

Did you have your first period in the last year or two? It's pretty common to have irregular periods at the beginning until your body falls into a regular schedule. Even then, a lot of people deviate by a week or two--I could never predict the exact date of my periods.

It looks like you're not that irregular, since you had periods 8/26, 9/30 and 10/19. However, your mind keeps going back to your old schedule, because you say that in October you were 2 weeks early when, according to your new schedule you were only one week early. Now you're due the last week November, so you should expect it any day now. You don't need to worry about pregnancy unless you don't have a period by mid-December. Your body is adjusting to a new schedule, that's all.

Regularity when it comes to periods comes and goes. That being said I would wait a little, maybe another week or so, and take another hpt test. Don't worry about buying the test, if it helps go to a store with a self-checkout, or go behind the guy buying condoms, enema kit, cucumbers, and carrots.

Trust me when I say that the clerks don't care and have seen weirder purchases, and you're 19 how would your parents know about a doctors visit? I would go there just to figure out your periods and that's perfectly valid. At this age your parents only have rights to the info you're conformable giving them.
