Please help...


Really hoping I get some explanations. So I'm almost 20 weeks. Had a normal day, actually had an ultrasound today and everything looked good, been eating and drinking enough fluids. Then about two hours ago, my stomach got really big and really hard out of nowhere. I keep reading online that yeah, it's normal when the baby is growing and the uterus is growing for the stomach to get tight and hard... but this wasn't gradual. It got hard very suddenly, like a lot of air or something just blew up my stomach, and I keep getting on and off cramps. Should I worry? What could this be?

Then my SO's mom says I could be going into labor. Like uh... WHAT?! Please tell me I'm trippin 😔😥
