I am 26, and totally healthy (I had a full physical 2 weeks ago). My cycle has always been like clockwork, so these past few months are really throwing me.
In February, I was expecting my monthly around the 24th, but it didn't come until the 1st of March. Extreme stress was the reason for that, as I had been caring for a sick puppy who died at that time. When it did come in March, it was normal, so I didn't think anything of it. Well, I have missed this month completely. The obvious answer would be pregnancy, and that is the 1st thing I was tested for, both at the doctor through blood and urine, and then at home a week later. Negative. I was also checked for infections and other medical issues that might cause it to stop. All tests came back normal. My stress level is fine, and there hasn't been a change in my diet and exercise lately.
Is there anything that the doctor could've missed that could be screwing me up? I am really starting to worry.
