Can I have children?

Laina
I have a regular period. Never had an infection or STD. The only medication I take is Adderall (amphetamine) for my A.D.D. 
Me and my partner have been having unprotected sex for 1yr and 4 months. But, I can't get pregnant. Also I have been under a lot of stress/anxiety lately due to hard college work, and my job. Can ADDERALL affect me having children?
