When is cramping a cause for concern

So I’ve had cramping the whole time since I found out I was pregnant (I’m almost 5 weeks) but it seems to be getting slightly worse. It’s on and off only lasts for a few seconds at a time sometimes it’s all over my lower abdomen and other times it’s only on one side. No spotting or bleeding just a lot of cm. Should this be a cause for concern because it’s getting worse?
