It's so hard to tell!! I keep thinking I feel little wiggles toward the right side of my tummy but then I'm not sure if it's gas...but no gas comes out. Or maybe it's just my tummy bubbling away?! It's been like this for a few days now, I'm sure in the next 3 or 4 weeks I'll be able to tell the difference! . For now, I shall cherish it whether it be a fart or not .
