Breast Clinic Referral

Hi everyone.I was referred to the breast clinic for an urgent referral last Friday and I haven’t heard anything yet. Does anyone know how long it takes to get the appointment through? Also if it’s by phone or post?I’m so scared and desperate for the appointment. I had breast pain, underarm pain, bleeding from the nipple for the last 2 months. I went to my local urgent care and they found a lump. I  just want to know when the appointment will be/ be made.thank you
