Can someone please help me! I am having all of the symptoms of it starting my cycle (tender breast, headache, peeing tons and nausea) for about 2 weeks now but nothing. I started spotting the day I was to start me cycle (and you can set your watch by my cycle between 27-29 days) and have been for 3 day after. I have had a blood pregnancy test and they said it was negative. Could it be that the blood test was wrong and I am pregnant or can this be my period?

What did your doctor have to say after the negative test? Blood tests are generally accurate. If you're still having symptoms and negative tests results with no period I would go back to your doctor and have him or her help you determine what's going on. There's no way for anyone online to diagnose you. You could just be having an off month, but it's best to have your doctor help you determine if it's nothing wrong or something that needs to be addressed
