Before you tested, I mean?

Our timing last November was really crappy...we only managed to have sex one time two days before ovulation. We'd not managed to conceive for over a year of perfectly timing sex, so I assumed there was no way I could have gotten pregnant. Completely positive I wasn't pregnant, had already gotten a new bottle of wine/box of tampons/carton of ice cream. On the flip side I had many months I was sure I was but wasn't.

I tested the morning AF was due only because my temp was still up. When it came up positive I sat on the toilet for a good 5 minutes just staring at the test in shock.

Did you know or think you were pregnant before you tested or were you as surprised by it as I was?
