So here it is.. AF runs like clockwork for me. Every 28/29 days she is there. Well not this month. She was a no show. I was do on 3/15, had some "spotting" for about 3 days starting on 3/17 (and by spotting I mean occasionally while wiping i would get what looked like a mix of discharge and blood. Maybe once or twice a day). And here I am on day 10 and my pregnancy test came back Negative. What else could this be. I have never missed a period and like I said, I run like clockwork. I know all about how stress can cause it to miss or skip but that's not a factor. I do have some other symptoms like raging mood swings, a very sensitive nose, I get these mini headaches and I never get headaches... Any input would be helpful.
