Wondering if I can pregnant

Caydan • 21! Love to travel! Student!
I'm 21 and curious if I can get pregnant. I've had my hormones tested a year ago and I've been with my boyfriend for 2 in a half years and we've never used protection and I've been off the pill for 2 years and haven't been pregnant yet. Should I be worried and should I go to a reproductive doctor to get tested?
