Do you think birth control helps some ppl get pregnant?

So I'm trying for baby #3. :) BUT.... I'm having a hard time. So when I got pregnant for my daughter I was 16 & I was on the pill when I got pregnant. 6 months later I found out I was pregnant for my son (which will be 4 in October) & I was on the patch when I found out for him. I haven't been on any birth control since finding out, hubby & I have used no methods to prevent pregnancy but also wasn't "technically trying" but we have been tracking periods & everything on here actually trying for the past 6 months & still nothing. So I guess my question is do any of you ladies think birth control may work opposite for some women?
