Getting your tubes removed

😱 im thinking about getting my tubes removed. I have 4 living kids from ages 15 years old to 9 months old im almost 30 . I've had a couple miscarriages. My last living child was premature i was very sick and ended up in the hospital for 2 weeks until I gave birth. Then i ended up pregnant when my baby was 4 moths i ended that pregnacy. I don't think i want any more kids but i don't know if i can go thru with doing something permanent knowing i ended my last pregnancy.
