Cramps are really worrying me.

I am 24 weeks, I haven't cramped since the first trimester. Last night at work around 9:30pm cramping; like a dull period ache started. It's now 7:30am & it's still going. Just a constant ache. Anyone experience this. My doctors office is closed today & tomorrow so I probably have to tough it out till Monday anyways. Just really worried. This can't be Braxton Hicks, because it's just a constant ache & not like it's coming in waves. The babies still moving well so I know he's ok. Just starting to worry myself. 😞
