It has been over 40 days since my last period, which was February 14th 2008. My cycles are normally no mare than 33 days apart and that is pushing it. I have taken 3 pregnancy tests and all are negative. One of those tests was a urine test at the doctors office. At that time the doctor also checked my thyroid and glucose, they were both fine. They did not take a blood pregnancy test. I did spot almost 2 weeks ago but nothing too significant, and I am extremely fatigued. I was not stressed prior to this set of events, I am a healthy adult, with nothing new in my life changing that would explain this.... has anyone else gone through this, and could i still be pregnant and just ovulated much later in my cycle that it would not be showing up yet? Please give me your advice. :confused:

did your doctor check your hormone levels too?
