Feels Like a Tummy Bug 😞

I'm 6 months pregnant and my tummy has been hurting off and on today right down the middle. The past couple of days I've been uncomfortable and I know my baby is growing and my stomach is expanding more. The only way I can describe how my tummy is hurting is comparing it to the stomach flu when your stomach sort of cramps up. I can feel my baby move and I read that's a good sign, means he's not in distress. Last night I ate enchiladas ( without red or green sauce ) and had Oreos, which I haven't had either one of those since I became pregnant.
