Body itchy & pregnant

So just now I realized that I've been itching all over my body my tummy obviously I chalked it up to the baby is growing but my almost my whole body? I realized I started scratching my hands and feet as well then I decided to look up itchiness during pregnancy & came across "Obstetric Cholestasis" and I'm freaking out I've just hit my 31 week and I guess this "OB" starts right at 3rd trimester 30 weeks it has to do with the liver that if left untreated can lead to premature birth or stillbirth which terrifies me... I'm going to ask for blood test from my Dr just to be safe than sorry. But has anyone else gone through this? I mean I'm very alert with my body this is the first day that I'm itchy maybe I'm over thinking.. I'm really hoping that I'm ok my baby is ok and my liver is ok. I hope it's just my skinh being sensitive
