fibroadenoma Biopsy advice

Hi, Im just looking for some advice. I’m feeling terrified and lost and scared. I’m in my 30s and found a lump the size of like half a grape and have been to the great clinic. When I went to see the regestra he said he thought it would be a cyst but when I went in for the ultra sound she said could be fibroadenoma but because some of it wasn’t smooth she wanted the biopsy and did some biopsy’s and scanned my underarm. Felt like she was clicking the mouse under there when she was scanning. Then I went back into the first room. They have booked me an appointment in 3 weeks time for the results and didn’t give me any inclination of if it’s anything or not as they can’t say until they have results. I’m just so scared. I don’t know what to do with myself. Do they call you sooner if they find something or do they wait unti The appointment? I’m just so so scared.
