more kids?

I had my fourth baby 2 months ago. I swore to my husband that this was it and i didn’t want more. I even said if i had a c-section i would get my tubes removed to prevent the chance of a future pregnancy. That didn’t happen as baby was born vaginally. Now here i am, i don’t know how to tell if i’m done having kids. i feel like i want another. Do people have 5 kids, am i crazy for this thought?😳
