I did. I 'just knew, just a sense I had. It was on 30th June 06 (i think it was about 6 DPO) and I was all of a sudden really really vague and then I just thought "i am pregnant". We had our 30th June party at work (financial sector, so its a big deal!) that night and I remember leaving early because I was just so tired by 8pm. So I tested a few days later, and sure enough, I got a positive.
