CLEARBLUE Pregnancy Test digital berbaloi tak? Berapa lama result dia boleh tahan?

Hi mommies. Sekarang i roughly dalam 4 weeks pregnant and first time pulak tu. So i guna je pregnancy test disclosure tu for now Alhamdulillah semua double line and now masih fikir nak beli ke tak yang digital tu. Sebab ada baca pregnancy test digital (weeks) tu result dia tahan 48 jam je. So can anyone help me?
