Sayang, baby movements tu memang normal and healthy sign! But since you're having chest/upper belly pain (ulu hati), please see your doctor or go to the clinic soon, jangan delay, okay? Pain during pregnancy kena check to be safe. Baby's position at 35 weeks boleh berubah-ubah lagi, so gerak sebelah kanan tu very likely normal je. But the pain you're feeling, that one kena confirm with your doctor whether it's just ligament stretching or something else. Better to get checked dahulu, mama.
