Pregnant with twins and want to have a natural birth!!!


I’m currently 13 weeks pregnant with fraternal twins, their doing great!!! But since i found out i was pregnant i was set on having a water birth, I’m not sure if i still can but if i don’t i would like to have a natural labor and delivery. I don’t want a c section at all but I know if I have to get it of course I will to ensure the safety of my twins. What can prevent me from having a natural birth?
