They found a good sac in the uterus, with an embryo of 5.5mm with a heartbeat of 128bpm.
They gave me a gestational date of 6w2d.
Two days ago (now known to be 6 weeks on the nose, not 6w4d as generally guessed when I first presented based on my LMP) they did a blood check of my HCG levels. They came out at 50, 001
They didn't do another HCG test today so I can't say if they have doubled or not.
Does that level seem high for only 6 weeks? I have read so many womens levels on here and they are much, much lower than mine for about the same gestation.
The Dr did say he couldn't see twins but it's very early so a second one could be 'hiding'.

I know the HCG ranges for healthy pregnancies are pretty wide, but could this indicate a multiple pregnancy? Or could this be a molar pregnancy? They would be able to tell if it was a molar pregnancy at this stage on US wouldn't they?
This is my first pregnancy.
Any thought much appreaciated
