Every time I went through a cycle, expecting AF and wasn't pregnant, I SWORE I was. I had all the pregnancy symptoms there were. The two times I got my BFPs, I did NOT expect it. I thought it was just a normal cycle because I felt oddly "normal" and got no symptoms. No feelings, that I know of. Both times, I tested in preparation for something (the first time, I had to test to start Clomid, and the second time I had to test to get x-rays done the next morning).
