alley

I live in Florida my insurance is there and ob dr I came to California for a couple of weeks I turn 11 weeks and 3 days this is my second pregnancy but I was reading and it said online that I can get a blood test early as 9 to 10 weeks I’m not so sure how true it is but my first pregnancy I didn’t found out I was pregnant until I was five months when I went to the OB doctor they told me right away during ultrasound I was having a boy I never had the blood test before or were to actually get it done I don’t have my OB doctor here do I have to make an appointment with a new away just for that blood tests or I can go anywhere?
