I'm 19 years old. And I sometimes smoke cigarettes and weed. I've been with my boyfriend for almost 3 years. Maybe a year ago we found out we had chlamydia and went get treated for it. A few months after I took a ovulation test and was'nt ovulating. Does that mean I'm infertile. Also I took a depo shot maybe 3 months ago. How long will it take before I can try again to get pregnant? I'm very scared that I can't get pregnant. This all happened maybe a year ago.

You need to bring your concerns to a medical professional.
We cannot make any kind of diagnoses over the internet.

The depo shot has many different side effects and that could well be skewing any other tests you have taken.
