Nipple crack

Mommies ada experience nipple crack? Dah more than 5 days. Baby 20days jenis sedut laju & terlalu menyedut nip. Dah apply nursing butter & susu sendiri 24/7 but still crack tak baik2. First time jadi cemni. If continue df, nip boleh berdarah ke? Or should i just breastpump? Any experience?
