With my DD I tested a few days after my period because I was not expecting to get pregnant, but I had never missed a period before in my life. The line was really dark as soon as the pee hit the stick!
With my second pregnancy I thought my cycle was just a long one and didn't test until around day 40. I took a digital and screamed when it just popped up PREGNANT after a short wait.
With this pregnancy I was anxious because we had been TTC for 7 months, so I became a pee on a stick addict. I peed on them constantly.

At 9 or 10 dpo I got a faint pos line on a FRER. It did make me more nervous though, because I found out at 3 weeks...I kept waiting on pins and needles to miss my period. It's also making the first trimester go by so much slower having found out so early.
