Unmedicated birth methods without visualization?

Hi guys!

I'm a FTM newly in my second trimester. I really want to have an unmedicated birth if possible and am looking for techniques I can research and practice for the birth. Unfortunately I have a condition called aphantasia where I can't visualize at all -- it's just blackness. I know visualization is really prominent in a lot of things like hypnobirthing. Just looking for some suggestions. Thanks!
