When do you go to the doctor?

Hi everyone I have a question. When should you go to the OBGYN? My husband and I have been trying for a while. Today was the fifth day of my missed period. So my husband and I decided I should take a test. Well when the first one was positive I tried a few more and they were positive too. I think I'm 4-5 weeks along. I really want to go to the doctor to confirm everything but from what I've been reading online I shouldn't until I'm 8-10 weeks. Is this true?
