Hi bb38,

Unfortunately, it is possible that a miscarriage may occur, but it's not a definite. This early on, it really is a matter of waiting and seeing. Your doctor will likely do another check to see whether there has been an increase or a continued decrease. Depending on what the next level shows, an ultrasound may be done.
