Giving birth to twins at 35.2 weeks is considered preterm, but with advancements in medical care, there is a good chance that they can survive outside the womb. However, their health and development may be affected, and they might require specialized care in a neonatal intensive care unit (NICU). It is important to consult with your healthcare provider who will assess your specific situation and provide guidance on the best course of action. They will monitor the babies closely and take necessary measures to support their well-being.
