Low sugar?

I posted this last night but I’m currently 18 wks and almost every evening my sugar gets super low to the point where I’m shaking. I’ve never had problems with my sugar til now. Is it normal to have problems while pregnant? Has anyone else dealt with this? Please any advice would be so helpful 😩
