Ohhh I know exactly yang feeling tu, towards the end of pregnancy semua jadi pelik kan! A few of my mum friends had the same gatal-gatal at night, especially in the folds, and it's usually just dari sweat, heat, and friction tu lah sebab perut dah besar. Lepas deliver sikit sikit hilang pun. But sebab you're getting close to due date and it's bothering you at night, better check with your doctor just to make sure it's not anything like yeast infection or skin irritation, takkan lama pun nak pergi clinic kan, and they can give you something yang safe for pregnancy kalau perlu. In the meantime, try keeping that area super dry (cotton undies, change bila berasa wet or sticky), and some of us swear by loose, breathable clothing at night sebab tight clothes just trap heat kat situ.
