Can switching from the Depo-Provera shot to birth control pills make you sterile. I've been trying for 2 year now?

Absolutely not! The source of any fertility issues do not lie at the doorstep of the pill. In the' olden days' doctors placed patients on the pill to regulate irregular or sporadic menstrual cycles. Once the pill was stopped, the irregular cycles resumed and the 'pill' ;was blamed. See a OB gyn to find out why you have not become pregnant with 2 years of unprotected intercourse.
