Hi, I'm a teen and recently I've been getting this weird gassy pain like the week of when my period usually comes but has not. And it's hard to explain, it's like when you're just sitting there and you can hear your stomach make noises and you can feel a uncomfortable feeling within your stomach. Like my "pain" feels like "butterflies" to the max or like, when you're hungry and your stomach feels empty and starts to hurt a little,thats what it feels like. I just want to know if it can be from tight jeans? or if it's normal or not? or do I have to get this checked? Like, this is my second time feeling this way in a month.
