Covid & upcoming appoitment

My anatomy scan is tomorrow. I need to call to confirm my appointment and im nervous to tell them I have been coughing. Not because I have covid. But because I just have a cough in general that I've had for almost a month. Its not consistent and mostly during the morning and night. My son had croup 3+weeks ago and we all got sick from that. Its just been kind of lingering. Do you think they will still see me since I have no other "symptoms"? I'll understand why but still will be really bummed.
