Aiyo, jangan worry lah, ini standard procedure je kalau HB drop macam tu! A few of my mum friends juga kena buat checkup yang sama during pregnancy, cuz doc nak make sure takde bleeding issue atau infection yang buat HB turun. Some of them siap kena more tests lagi depending on results, so yours is actually quite normal, doc is just being thorough, yang tu bagus! Kawan-kawan yang cakap takpernah dapat mungkin HB drop mereka xseteruk, or maybe they didn't follow up as closely. Just do the tests lah, it's quick and it'll give doc the full picture so dia boleh help you properly.
