A blood test it's your choice if you want to have it done some people say they deny it but I had it done everything came out normal but my mom had tested positive for it with my little brother and it was wrong he came out just fine
That far along I dont think its the blood test, I think its the needle in your tummy. My mom had to do it with both my sisters
The needle in your tummy is when you test positive I believe, but don't hold me to that, I denied the test both of my pregnancies they are wrong alot of the time and just cause alot of stress, I figured if my baby had any issues I would cross that bridge when I got to it and would not love my baby any less
Under 24 weeks they due the blood test
