Aiii, bunda, ni boleh jadi hormonal imbalance or remnants from postpartum recovery lah, especially since anak you baru 1.5 tahun, but heavy bleeding for 5 days after 2 months gap really kena check dengan doctor, okay, jangan delay sebab ni tak normal sangat. A few of my mum friends had similar situations and it turned out either masalah thyroid or uterus lining yang tak settle lagi after giving birth, so kena scan to be safe! Lepas check, boleh tengok balik dengan gynae if ada polyps or hormonal issues, but go soon ya, bunda, better safe than sorry!
