Going 4 my sonogram 2day!
Thaks u guys I sure will! I find out this week....
Yes higher than normal HCG levels are the first determining factor when having multiples, but like AnnieBrooke said the range is so wide at this stage. I would have your doctor monitor your HCG levels if you are concerned.
Another sign is 'extreme" pregnancy symptoms, like excessive fatigue, morning sickness, or even weigh gain. I miscarried twins about four weeks ago at 9 week gestation. I knew all along that it was twins, I just had a "gut feeling" and I was right, but neither of them had heartbeats.
Take Care and keep us posted

The range of "normal" in hCG readings is really, really wide. I don't have the chart in front of me, but I remember being amused to see the thousands of numbers that would be considered a normal reading within a given week of pregnancy. The only thing that clued me to the possibility of multiples the two times I had twins was that the levels rose really fast, more than doubling and at times tripling in two days. But I don't even know if that is definitive.
ps -- One lady on this site mentioned that when she was pregs with twins, her first reading (at about 4 weeks) was 70.
