So one side of my tummy is hard and one is soft

Okay so sometimes your tummy can feel different on one side because of normal stuff happening inside your body, like digestion or gas, especially around your period. It's usually nothing to worry about.

Like, your belly literally has a lot going on in there! Your digestive system is always working, and sometimes that can make one part feel a little firmer. Also, during different parts of your cycle, your hormones can cause bloating or make things feel a bit different inside. It's not uncommon to feel things like this, especially when your body is changing and growing so much.

If it feels really sore or painful, or if it doesn't go away, you should definitely tell a trusted grown-up. They can help you figure out if it's something that needs to be checked out.
