Cream / gel
Welcome to healthcare magic.Atrophic vaginitis
has decreased wetness ( mucous secretion ) due to lack of estrogen hormone. When you touch the mucosal part for wiping, it leads to friction and slight blood comes out.
You need HRT
as well as local estrogen cream / gel to overcome this problem.
When you visit doctor on monday, request for estrogen cream / gel till HRT starts acting.
I hope my answer was helpful.
