Fetuses don't percieve pain

Agree. My nephew born 29 weeks...he feel pain then. He cry when nurse stick needle.

You are just assuming that they are crying from pain, because you saw something happen that you would think was painful if it happened to you. Preemies are not crying from pain. They are crying from environmental changes that their system is not ready for yet that create an unpleasantness. Just like a full term will cry from hunger, or being bathed, or having their diapers changed.

So in other words, before 35 weeks, it hurts more and the whole system , and after 35 weeks, pain is localized.

No. The neuronal connections are not mature enough to turn a perception into pain.
