When to go to the doctor??

I have my first apt set for around 10 weeks to see the doctor. This isn't my first pregnancy and was just wondering when others are going in. I was just shocked when people are on here posting that they've gotten blood work 10, 11, 12 dpo. Makes me wonder.....am I just being to relaxed??? Nothing is really going to start happening or be seen so early. I can understand if you've had problems in the past. Just wondering. Thanks.
