Baby movements

I'm 14 weeks pregnant with my second and baby doesn't usually move much at all during the day, it will pop up every now and than but at night it has a rave party in my uterus and doesn't stop moving pretty much all night... which wakes me up constantly through the night....does anyone know how to calm baby at night and get it to burn its energy during the day? I only got 3 hours of broken sleep last night as I'm a very light sleeper which means i wake up to every movement and my 1 year old had been having a rough week with the flu. Also is it normal that my lower abdomen feels like its bruised and has a lot of pressure? I don't remember having this pain with my first. TiA
