Hi! I know the only certain way to determine if you are having twins is through an ultrasound, but I like to daydream. I had IVF - 2 5 day blastocysts. My HCG levels were 566 on DPO 15, and 2384 on 19 DPO. So far ... does this look like twins?:) I looked at the chart here, advancedfertility.com/earlypre.htm, and it certainly looks like it is a really strong possibility, but wanted some input!
Re: HCG Levels Indicating Twins?
3 weeks LMP: 5 – 50 mIU/ml
4 weeks LMP: 5 – 426 mIU/ml
5 weeks LMP: 18 – 7,340 mIU/ml
6 weeks LMP: 1,080 – 56,500 mIU/ml
7 – 8 weeks LMP: 7, 650 – 229,000 mIU/ml
9 – 12 weeks LMP: 25,700 – 288,000 mIU/ml
13 – 16 weeks LMP: 13,300 – 254,000 mIU/ml
17 – 24 weeks LMP: 4,060 – 165,400 mIU/ml
25 – 40 weeks LMP: 3,640 – 117,000 mIU/ml
There is a huge range of what are considered normal levels. As you said, you won't know without an ultrasound.
