PCOS body "resetting" after pregnancy??

I will be 18 weeks on Friday after a year of infertility treatments, iuis and a miscarriage due to PCOS. I was wondering if anyone with PCOS, has your body "reset" after having a baby? The second baby did you have to go through the same mess to get pregnant again? Just wondering if I will have to go though infertility again? Any stories or thoughts are really appreciated!
