My husband and I have been TTC for a while now. I got a hsg dye test done on the 21st to make sure my tubes are clear, and the are clear. I usually have brown bloody mucus when I'm fertile for about 2 days. This month we had intercours on the 22,24,25,and 26th. I have had bloody mucus for about 3to 4 days now with a very slite cramping. What could this be?
