Freaking out

I've had maybe 7 sips of wine on 3 different days and I'm just freaking out because the wine was strong and I'm scared of Feta alcohol syndrome. The only reason I thought it was okay was because everyone says a little wine here and there is fine but I'm still extremely worried. I'm not gonna drink anymore and I'm waiting for my ultrasound but can anyone put me at ease. I'm 16 weeks pregnant. It was Cabernet Sauvignon so if u drink that you know it's kind of a strong wine and I only had like 7 sips which is prob half a glass not even.
