I'm worried now😥

So I'm high risk due to losing my son last November he was stillborn. I'm pregnant again and I'll be 6 weeks thursday. I Went to the doctor last Thursday and she told me I wouldn't see the high risk office until around 12 weeks.... well they called me this morning saying they got a referral for me and I needed to come in ASAP. I have an appointment on Friday. Now, I'm really worried that something may be wrong!! Keep me in your thoughts and prayers ladies
