What to do before doctor's appointment at 8 weeks?

I thought that since the first trimester is when the baby has the highest risk, that we should go have a check up as soon as we get a positive pregnancy test. Husband called a doctor and said that she doesn't see patients until they are 8 weeks pregnant.

I'm just wondering is there anything I can do to help the little bean stick while waiting for our doctor's appointment? I don't smoke or drink so anything besides that. I'm also already taking prenatal vitamins since we started ttc this month.
