Hi Bubwishes
Your HCG increases are well and truly withn the normal range, and perhaps yours doubles over 72 hours instead of 48 - that would seem consistent with the increases.

I have had a lot of worry with HCG and have come to the conclusion that everyone is different, and look for your own individual pattern. My doctor has reassured me that she think mine are good number, and although the science says doubling 48 hours, this is for 70% up to 6000 hcg then it slows, and the other 30% that have a slower rise like yours (but steady, that is the pattern) - still have wonderful babies.

Bubwishes, please try and stay positive for bubs, - have your hcg done again in a few days if you wanna check if 72 hours is more your pattern.

Good luck, and please let me know how you go

Sam
