Ahhh beta HCG readings lah! Mine was around 250+ at 4 weeks with my singleton, then doubled nicely every 2-3 days, tu lah yang gave me confidence semua okay. A few of my mum friends with twins had readings yang lebih tinggi, like 400+ at the same timeframe, tapi honestly setiap person different je based on implantation timing and how the embryo developed. Best thing is kalau your doctor monitor the progression over time rather than worry about the exact number, sebab that's what really matters, the pattern lah yang penting! What did your doctor say about yours?
