Anytime you have sex, protected or not, you risk pregnancy.

When is your period due?

I have not had a period in over a year now or less

It is possible to be ovulatory when being amenorrheic.

Basically, this means that you can still ovulate when you are not getting your periods.

It is now up to you go make that doctor's appointment to find out why you are not having your periods.
