Cramping? 13 Weeks

Hey ladies!

I'm 13+6 and I'm experiencing slight cramping in my lower abdomen and lower back. I just wanted to find out if anyone's experienced this, and if it's normal? I've heard about round ligament pain, but read that that's more of a sharp pain as opposed to the dull achey pain I'm feeling.

Any thoughts?

Thanks so much ladies ❤️
