13w 3d with period like cramps; anyone else?

Brionna
This is my second pregnancy, and I remember getting cramping early on with my first, around 4-8 weeks along. I also had some round ligament pain when I sneezed or got up too fast. However, the ones I'm getting now resemble mild/moderate period cramps. Kind of dull & they're there for a little while and then disappear. Anyone else?
