Thanks Lily. I just went back over my HCG amounts, although I didnt get as many done as you, they were

4w3d - 480
5w - 3301
7w2d - 171,000
8w - 250,000

So I guess pretty much the same!!!

I think when the HCG levels are at 250,000 at say 4 weeks, then there would be more indication that there is possibly more than 1.
