Breast Cancer clinic still seeing patients within 2 weeks?

I was referred to a one stop clinic by my GP a week ago after finding 2 lumps and bleeding from nipple. My GP said that the appointment would be within 2 weeks. A week has gone by and I haven't been sent a letter yet. I'm quite anxious and with everything going on in the world I knew I may have to wait but this week has been awful. Should I wait the full 2 weeks to chase it up?
