Call ER or wait?

Probably dumb question. But it’s currently 3am and I just woke up in pain. I’m 20 weeks pregnant and the pain is constant and located on the upper right side of my stomach. I tried googling and it obviously ranges from not serious to serious. This is my second pregnancy, is this normal? It hurts more to move, breathe, or stretch the area. But it’s a constant pain and has been constant now for 20 minutes. If I call the ER I know I’ll be told most likely to come in, which means waking my toddler up and my grandmother (currently only have one car mine is in the shop) to come get us

Not having any bleeding or lower cramping. Had headaches for several days two days ago. But I also wasn’t sleeping well at all. Since two days ago I’ve been sleeping better and not having headaches.
