I had my two children without epidural, much because the labor was not too long, around 5-6 hours.
For moms who considered epidural, don't feel guilty at all cos as some moms might have shared, their dilations went much faster once epidural is administered. Reason being the body can relax more so baby can ease her way down without us fighting the contractions and stress the mind and body. So, if labor went on way too long, the doctor probably thinks it is a better idea for mommy to take a rest using epidural, let things proceed faster and save energy for pushing.
For moms who considered NO epidurals, but a little worried about own pain threshold, well can try Hypnobirthing. simple theory behind it is that by telling ourselves every contraction is us working with our baby together, it can be nice and beautiful. eg. Imagine every contraction is like a blue satin cloth wrap around the belly and tightening, or imagine a flower blooming, or breathe in and breathe out in a 'J' shaped direction which helps breathing baby outwards... etc. It is possible to channel that fearful thought of contraction pain to become a construction 'sensation'. Just be in your own world and IGNORE THAT MACHINE that measures contractions..YOU are the one who knows BEST what's going on in that body!=)
If you want more support during labor, try engaging a doula or go for hypnobirthing classes. My friend engaged a Singaporean doula, Ginny whom I had attended her hynobirthing class. Absolutely empowering. After the class you will be way more comfortable with the idea of childbirth as you realised there are so many things going on during labor, our body is very much up to the job!
All the best and have a safe delivery!
