I'm 15wks and cramping with no bleeding

So I had a gender reveal yesterday and it was beautiful we are having a boy. When we got home I ate pasta salad and a Pepsi. I have been cramping all night. All throughout my sleep when I woke up to pee I was still cramping. Im not bleeding and I have googled it. It could be my uterus stretching due to me being in 2nd trimester. But I am very uncomfortable. I've been drinking water and I want to see some feedback before I call out for work. This is my first pregnancy, should I work through it or stay home????
