Did having a baby help with infertility?

It took me 6 1/2 years, 3 failed IUIs, 6 failed rounds of clomid and 6 failed rounds of letrozole to get pregnant (I did conceive naturally not on any fertility medication) I was trying to hear stories from others who went through fertility struggles with their first baby did you have issues conceiving with your second child or did having a baby make it easier to conceive again?
