membrane stripped

Natalie • 22, Married & mother to my beautiful Ayva Raylynn.. Pregnant with baby #2 :) baby dust to all of you beautiful ladies!
My friend had her membranes stripped and has just started bleeding more like spotting she doesn't have any pain she's wondering if she should just wait until she has contractions or go in as an emergency she doesn't feel like it is in emergency now but the doctor said if she started bleeding to go in. Do you think it's wrong for her to wait until she has labor pains?
