So the most relevant pieces of information I can think to provide are I had protected sexual intercourse last night, and am on the pill, which I have taken continuously (skipping my period) for like 3 months (I have been on the pill itself for over two years) and I noticed today I was having brown discharge, which continued to come over the course of the day. This hasn’t happened before except at the beginning or end of my period (if I were to not skip this month it would come in 1.5 weeks)
