Aiyooo sayang, nenas tu memang old wives' tale je, takda scientific proof pun that it speeds up labour, so jangan harap sangat! I get it, you want natural birth without induction, tapi honestly dengan GDM 37 weeks is already quite far along and baby's safety comes first, so doc-induced birth tu actually the safer choice untuk both of you. Better to go with the induction plan than risk complications, takde point trying all these shortcuts when medical team dah give you the best timeline for your situation, you know? Check with your doctor about your concerns, but trust their recommendation la, mama
