Keep yourself as healthy as possible throughout your pregnancy. Para di ka high risk, less chances of complications too.
If hindi ka pinagbe-bed rest, do some light exercises. They're good for blood circulation. May exercises din to help prepare your pelvic floor muscles. Marami nyan online to help with labor and postpartum.
Practicing breathing exercises. They can help you deal with the contractions.
Pack your hospital bag early :) Not exactly related to childbirth itself but it would save you from stress kapag nafeel mo na na kailangan mo na pumunta sa hospital/dr.
Good luck mommy!
