Af was supposed to come last Monday and she still hasn't arrived. I took a test last week and I thought it was a positive so I called my doctor. They took a urine test and it came back negative so the nurse told me if my period doesn't come in 7-10 days to test again. Well I took another test and it is negative. Yesterday I had some really light spotting that I noticed when I wiped. It didn't last very long. I don't know what to think.
