I need advice! My last period was the 1st of March. It lasted 3 days, very light (which isn't normal for me), light cramping (mine are always horrible), and milky white discharge. I ended up having brown and pink discharge as well. I am now 7 days late for my period. Boyfriend and I have been trying to conceive for 10 months now, this is the first time I have ever had this before. Im now having back pain and a lot of white milky discharge. What could it be?
