How much did each pregnancy change your body or age you?

How much has each pregnancy changed you, not just in terms of aesthetics and weight changes, but also your overall health? For example, maybe your metabolism changed or for some reason your blood pressure increased?

Do you feel like you started to age more rapidly after a certain point? Did pregnancy become harder with each one, or was it variable?

Did you ever consider not having more kids, just because of the impact it was having on you physically?

Thank you in advance for your answers :)
