Ablation or Hysterectomy????

I am 25, and I suffer from heavy bleeding, and severe pain in my left side. I recently was diagnosed with a uterine fibroid and an enlarged uterus. The doctor told me I could have an ablation, which there is an 85% chance it would work, or I could have a hysterectomy which would offer me a 100% result. I am needing advice on both of the surgeries. I have 3 kids, so I am done with that part. I just need advice as to the best choice to make. The doctor did tell me that if I had the ablation I would still need the hysterectomy eventually. Thanks!!!
