So I get dead skin on the very tip of my nipple every now and then well today when I saw it I went to get it off and pinched my nipple a little and white discharge came out. I have never had that happen. My boyfriend and I are trying to get pregnant. I went off the Mirena 12/11/17 and I am suppose to me ovulating this week. My last period was lighter than normal and was only 4 days long. Does the discharge have something to do with that? Should I be worried?
