Nervous about pregnancy

Hello everyone! So I took a text the other day and it was positive! I'm just scared because a few days ago I was sick with flu like symptoms and took some antibiotics for 2 days and then stopped when I realized I might be pregnant. I also lost my twins last year the 4th month of pregnancy. So I'm stressed ! Any words of kidness? Do you think those antibiotics and ibeprofin effected the baby?
