Mammogram Recheck

Trying not to get too anxious about this.

Got a call from the doctor that I need to have another mammo plus an ultrasound in a few weeks. They wouldn’t tell me more over the phone.
For those of you who’ve had this done, can you talk me through it?
Is this common practice? Mammo and ultrasound.
Do I need to bring hubby for support?
Will I get the results right away?
Anyway, so glad I went in. I’ll let you know how it all pans out.
Hugs,
Kimberley
