Hello, I didn't know that at 13 weeks it was necessary to give blood tests for Down syndrome, doctors didn't say anything about it. Now at 35 weeks the doctor asks me where my blood tests are. In the end they forgot to tell me. But during the ultrasound when I was at 13 weeks, they said everything is fine. Now 35 weeks, I am worried about the baby. Can I give any kind of test?
