OKAY I just started school about a month a go and I ve been eating out more and I see myself getting stressed and not sleeping well either. I have been also having sex(like 3 times) but I'm careful and every time I did it( well we never finished so he never came no even close to it) which was last month. And its been 2 months to this day 11/3/09 and I haven't had my pd. I think I could be pergent ( I know I can't spell) and I'm only 18. So I don't know what do I'm scared and I need help.

The wired part it I want to the doc 4 months ago and she told me ever thing is fine after I got all my test done.

How long have you been having regular periods?

Its common to have irregular periods at a young age. And just so you know, even if you think he never finished, there is always a possibility of pregnancy with even the smallest amount of sperm.
