Sharp cramps at 5 weeks?

I know cramping is normal in early pregnancy because your uterus is stretching. I’ve been getting these kind of sharp “waves” of cramps every now and then that are pretty uncomfortable and I have to almost breathe through them. It only lasts a couple seconds and I have no spotting just excess watery cm that comes out in a gush and has me checking for blood every time. Is this what your uterus stretching is supposed to feel like?
