Ok, here's the skinny. I had very ligh pink CM on Saturday afternoon/evening, moderate-heavy AF on Sunday morning/afternoon, moderate AF Sunday night, light/moderate AF today. I had really bad cramping yesterday and mild cramping today. AF is usually 6-7 days long for me with atleast three days of hellish heavy flo. I don't understand what's going on with my body. Should I see a doctor or just assume it's AF or could it even be IB??
