Home birth, water birth, natural birth, hypnobirth

Hi, I’m 17 and I’m pregnant with my first baby. I’m planning on having a water birth at home and I wanted to hear from other women about their experience as far as tearing? I’ve watched lots of videos about the pros and cons but I wanted to know if it’s less or more likely to tear while in the water. Also if anyone has tried not pushing and letting your body take over and breathing the baby out. I’m trying to have my baby as naturally and pain free as possible through hypnobirthing and calmness.

Any and all advice is welcome!
