Beta HCG brp? Singleton atau twin

Wah, tu soalan yang common betul! Honestly, beta HCG levels tu very individual, ada mummy dengan singleton yang level tinggi, ada yang rendah, so it's really not a reliable way to confirm singleton or twin. The best way is ultrasound scan je, even at 7-8 weeks dah boleh nampak clearly kung ader satu atau dua baby. Anyway, rasanya better you check dengan doctor kau since everyone's hormone levels beda-beda, and they'll know your specific situation best!
