I'm 4 days late & AF hasn't shown up. This morning I had a little brown blood or old blood color when I wiped, sorry TMI! I'm not having any cramping or breast tenderness which I get before AF comes. I took a test 5 days ago & I got a negative. I'm never late on my periods it's usually on time or the day before my expected period. I'm a little confused on what is happening. My boyfriend & I have been TTC for 15 months now. So I'm praying for a miracle.
