Dear Reader; Yes and that would be very unusual and good cause to see your health care provider. Dwight It is possible. I had all the signs and period was late for 3 weeks, I had nose bleeding, very sore and enlarged breasts, etc... and I was not pregnant. I wanted it so much that I just kept testing every morning because I could not believe that I was not pregnant. So as you can see it is very much possible to have all the signs and NOT be pregnant. Now I know that pre-menstrual symptoms are exactly the same as pregnancy symptoms! However, if you are concerned you can always go and ask for a blood test. All the best!
