Will the doctor be able to tell? I’m almost 29 weeks and I had my blood tested in the beginning and everything came back low chance so does that mean if the baby had it it would be a high chance? I also had the anatomy scan at 21 weeks and then another scan at 24 weeks and everything was normal. Sorry I’m getting anxiety about it because i drank the first 2 months of pregnancy because I had no idea I was pregnant, so I’m just worried.
