Hi new to the thread... No AF could I be?


Hi I am new to the site. My dh and I have been struggling trying to have a baby for over 4 years. I am always on time and they cannot find anything wrong with either of us. My last period was October 7th 2011 I am now 11 days late. I took a test when I was a couple days late and it was negative. I am worried and its just so stressful. Anyone out there understand how bad this feels? Or what could be going on? My diet and stuff hasn’t really changed. I dont have anymore stress than normal (other than the TTC worries.):grr: Any ideas?
