I had no idea with my first set till I lost one.

But with this last set, I knew straight away.

I was extremely sick, extremely tired, had super high hcg levels, high blood pressure, and a very very strong feeling. I also felt something wasn't right and at my 6 wk ultrasound, we found a second bubbs, but the sac was in the midst of colapsing.

I also have since worked out with my dates I was getting very definate positives off HPT's VERY early, at 9dpo it came up straight away.

Good luck, hon...
