Hi mummies, wanna ask to those who have experienced giving birth to premature bb... Is it safe for me to give birth at 35 weeks or either 37 week as I'm having contration n in bad pain??

It is still safe to reach 37-40 weeks gestation. If you are feeling an extreme pain or contraction then that means you are starting to labor. The contractions that you were feeling might just be Braxton Hicks. Ask your OB-gyne if you can take painkillers that is not harmful for the baby for pains.
