Period like cramping all day

Bradi • Mama to two precious boys (ages 2 and 4) 💙 and just found out we are expecting our third! 🥰

Has anyone else had some period like cramping across the bottom of the abdomen under the bump? Mine has been there all day. It’s sometimes worse and there have even been times that it stopped for about 10 mins but it’s been annoying me all day. I can’t get anything done because it’s so painful. It helps to be laying down but as soon as i get up it comes right back. What can i do? Is this round ligament pain or something more serious?
