I'm 18 weeks now and have random cramping but doesn't last long as long as no bleeding and they don't feel severe u should be ok
I had them periodically throughout, i think my dr said as long as theres no spotting its okay. im not 100% sure though. All i am sure abt is that i had them, and everything is still fine. But because everyone is different id call your dr tomorrow and ask a nurse what they think.Better safe than sorry.goodluck!
