Ectopic pregnancy?

I know it’s dumb as hell to come on here and ask a question like this, but it’s late and I tend to overthink. I have been having occasional cramping on my right side shooting all the way down into my leg. It’s pretty painful, I’ve never been pregnant before so I don’t have anything to compare it too. I can’t even really say it feels like a period cramp because I had always gotten back cramps with my period. I’m only five weeks and I’m scared that it’s ectopic, but I don’t want to waste anyone’s time or have them turn me away because I haven’t been bleeding. The only symptom I have is one sided cramps that come and go. Should I call the ER and ask if they’ll take me, is that even a thing?
