6 weeks and 5 days so excited

Hello ladies I just need some advice. I called my obgyn and they got me in at the end of the month on the 31st but I’m a little concerned because some people that I have asked that have been pregnant say that their primary care doctor have had them come in and take a test there and blood work but mine said I should be fine until my first prenatal visit on the 31st. What should I do try and get a test and blood work done as soon as possible or just wait for that first prenatal visit
