Lupron (leuprolide) for last 18days (ivf). Dealt with constipation. Now blood on TP after BM for 3 days- painful BM day it started. Should I call DR? Home remedy?

Call DR/hemorrhoids. You need to inform your MD of your constipation and bleeding post BM. It is likely to be hemorrhoids and an Rx can be given once your MD confirms the diagnosis by exam.
