Girls, due to problems with medical insurance and incompetence of some doctors I couldn't pass the first screening? I am already in the 14th week of pregnancy. At the 12th week I had an ultrasound screening at a private clinic, they said everything was fine, sent me for blood tests to where I am on record. In short, there is an ultrasound, but I haven't been able to get my blood drawn yet. So how important are these indicators? Can't I find out that the baby is okay, for example, at the 16th week? The gynecologist at the free clinic scared me, she said "everything. Damn. Good job. Where did you go before?". What
