tubes tied and I regret it! 😒

I have three girls, ages 9, 6, and 2. I got my tubes tied after my third C-section and now I'm regretting it! I don't want another baby at this very moment but I do want to try for a boy at least once more! I heard it was harder and very costly to get them untied. To make matters worse, my periods are 10times heavier. It's awful! Do anybody feel me?
