Mild itching on the belly is very common as your baby grows. I just used simple coconut oil, but if it gets too intense, definitely mention it to your gynac.
Beta, apply cold-pressed coconut oil or mustard oil on your belly, it helps. But if the itching is on your hands and feet, tell your doctor quickly, don't ignore it.
I had crazy itching on my belly in my last trimester. Keeping it moisturized helped, but my doctor also checked my liver enzymes just to be absolutely sure it wasn't anything serious.
Sometimes high blood sugar or skin stretching causes itching, but severe itching can be risky. Keep your skin hydrated and ask your doctor if you need a blood test.
