Abdominal cramping

Last night I woke up to the most painful cramps!! If you've ever had gastro or a stomach bug it felt alot like that but on and off. Moving positions didn't help water didn't help. After an hour they just stopped?? I didn't time them I was half asleep but they are gone now. I'm not feeling sickly or anything and today I'm perfectly fine. Is this something I should bring up at my next appointment? (Not for another week) or if it happens again get checked?? Xx also 32 weeks
