Haha don't worry, tak semestinya awal pun! At 38 weeks memang dah considered full term, so nurse tu just reassuring you yang baby boleh datang anytime now, bukan necessarily before due date lah. Weight loss at this stage is actually normal sebab body preparing for labour, so that's a good sign! A few of my mum friends experienced the same thing and some of them deliver on time, some even overdue jugak, tapi semuanya smooth je alhamdulillah. Just make sure you monitor for any unusual symptoms and keep in touch with your doctor or midwife regularly, okay? Good luck mama!
