Ok so I'm 17 and I think I'm pregnant if I am id be about 6 weeks. I was on birthcontrol for almost five years but two years ago got off it to regulate my period its been about two odd years since I've had a period so is it possible that I could be pregnant even thou I haven't had a period in that long?

The short answer is yes it is possible. It is less likely, however it is not unheard of. Women who don't get periods or who have irregular periods aren't immune. It may be unclear as to when you ovulate, but not necessarily impossible to ovulate. Seeing a doctor or taking a pregnancy test will give you some indication if you are. If you see a OB he could probably tell you why you do not have regular periods and further determine the probability of pregnancy without medical assistance.

Since you don't have periods regularly it is hard to determine how late, but I would wait another two weeks and try a pregnancy test.
