Amanda

Ok so af was supposed to visit last Monday but she still hasn't shown her ugly face. I've taken several tests and I thought one was a vfp but they were all negative. A nurse at my obgyn office said if af doesn't come in 7-10 days to test again. Yesterday I had some very faint spotting that I noticed when I wiped. It didn't last very long at all. When af does come she is usually heavy. I'm honestly not sure what to think. Help!
