A decision I will regret ?

Hello all, I am a 29F with a partial hysterectomy scheduled February 25th. My mom and people around me are swearing and afraid that I will grow to regret this procedure. I have 3 beautiful healthy kids that keep me more than busy on a good day. I am a single momma as well and plan to stay that way for a while. I had a choice between an iud(which wasn’t promised to stop my monthly cycle) and a partial hysterectomy. The goal is to better my blood disorder and my quality/longevity of life. Am I making the right decision ?
