Uterine pain during second trimester??

Aileen • Yazmín’s mom ❣️

Has anyone had lower uterine pain during their second trimester? This is my first, i’ll be 18 weeks tomorrow, i get so worried but could this be due to the body stretching or is it something i should worry about? It’s an actual pain/discomfort in my lower abdomen and SOME at my lower back.
