Round ligament pain or cramping?

Do the two pains feel the same? 13 weeks today and this morning and this evening I’ve had long time periods where I get really sharp and intense cramping sensations right under my belly/pelvic area. They last anywhere from 10-30 seconds before they go away. I get about 10 minutes before it hits again. I’ve heard RLP is typically on one side and maybe slightly higher up? I’ve also heard its supposed to get better if you change positions, but this pain isn’t affected by movement.
