Pregnancy Question!

My husband and I recently got married and I got off my birth control about ummm 6 months ago. I have hypoglycemia so I had to much estrogen from the pill and it was making me sick. I had been on birth control since I was 15 due to amenorrhea and endometriosis. It doesn't cure it just helps. Well now we aren't using protection since we are married. My question is, during my fertile window we did it like everyday I was fertile. And he did that inside as well each time. Well I started this time since it was so close to my period, and I'm just wondering if I could still get pregnant if I started???? 
My concern being that I have ADHD, and I have to take adderall which is a form of methamphine. Or prescription meth.
