Steroid Injection Dexamethasone for Baby lungs maturity, future effects on baby

Hello, anyone here got this steroid injection Dexametasone for baby lung maturity for the past years? I'mjust worried i got mine just today first shot since i will be delivering my baby for only 38weeks, so the ob decided to give me some steroid. But unfortunately i read some cleanical study the this kind of streroid can cause mental health problem to baby in the future like ADHD, hyper, or some later behavioural difficulties.. im so worried, does anyone here already observe side effect on your child or everything still okay?..
