Its hard to say from your note. It depends on what "markers" she was referring to, what scan you were having (i.e. how far along you are) and how well trained she was.
Being referred to a Peri is not an indication that something is horribly wrong however. It could just be for a follow up scan since their equipment is so much more sensitive and detailed.
Here's hoping once the peri takes a peek all is well!
