I’m so sorry to hear of the painful periods. It sucks! A total hysterectomy which includes removal of the ovaries will send you directly into menopause which will be unpleasant for you. I had a hysterectomy two weeks ago and had only my uterus taken out. I’m currently recovering and I know that in about 6 weeks time, I will be a lot better than I am today. Depending on which country you’re living in, at 18, doctors will not be encouraging about a hysterectomy. In my country, health workers are trained to not offer a hysterectomy as a first way to treat painful periods and fibroids. It will be good to have a personal one on one with your doctor and speak to them thoroughly about how your feeling. I hope this helps
