Am I going to loose this baby?

[sb1997]

Went for a 6 week early us.
Tech couldn't see anything referred me to hospital.
Had blood test 1700+ on Wednesday then today (Friday) is 1900.
They said they've risen but not a lot but haven't dropped ( which usally miscarriages drop hcg levels)
Scan booked for Monday.
Anyone else had this and it be ok? If not what happened? I've had no bleeding or cramps.
