stomach aches

I'm 5 weeks + 4 and have been having stomach aches rather frequently. I wake up almost every morning with one and takes a few hours before it subsides. Sometimes I notice it when I'm hungry but I know eating for two is way early. It send feels stomach tho and not lower. I just hope it's nothing bad. I haven't have any morning sickness. Just some gastrointestinal related issues. Anyone else experience this?
