38 weeks and cramps

I’ve been on and off again cramps since about 7 this morning it’s currently 1:25 pm. If I’m up moving don’t feel it only when I’m sitting. But it’s like a constant cramp not stop and come back. I know it’s common during pregnancy and for some reason it’s making me excited because it could mean little one may be coming soon. Anyone else get constant cramps while late in pregnancy?
