Hi,
They will probably be measuring the amount if hormones in your system to double check all is ok, as at 4-5 weeks is too early to detect a heart beat in baby, its around 6 weeks the heart starts to beat. They will be able to tell by comapring your blood tests to what they should be at 10 weeks pregant and if there is a chance that your dates are worng they will probably repeat the bloods a few days later to get a better idea whats going on.
Dont panic thinking everythings wrong, it is possible that you are 5 weeks pregnant and got dates mixed up, but the only thing you can do is wait and see what they say and do, and dont be afraid to ask what they are doing and why.
Good luck
