Light cramping

Andrea • Mommy to Eleanor 12/14/16 💜 and Julius 9/26/18 💚, expecting Penelope 2/17/22

18 weeks today with my second pregnancy. I've been having frequent light cramping since yesterday. I wasn't worried about it yesterday because I was sick the day before with intense/persistent nausea (Dr. said it was probably a GI bug), but now I've been having the cramps all day today. I haven't been too worried, but should I be? I didn't have this with my first. No changes in discharge or anything else. Anybody else experienced this?
