Okay I had cramps yesterday. They were really bad, and some today it tightness in your stomach that kinda hurts cramps. I also swam a lot today.

Okay, so cramps usually feel like a tightening or a dull ache in your lower stomach, and sometimes it can spread to your back or even your thighs. It's basically your uterus doing a little workout to shed its lining, which is what causes your period.

Swimming can actually sometimes help with cramps because exercise can release endorphins, which are like your body's natural painkillers. But if you were really pushing it, like doing intense laps, you might also feel some muscle soreness that could blend with cramp feelings. It's totally normal to have good days and bad days with cramps, especially when you're just starting out with your period.

To feel better, you could try a warm bath or a heating pad on your tummy. Over-the-counter pain medicine that a grown-up says is okay for you to take can also help a lot. If your cramps are so bad they stop you from doing normal stuff, or if they just don't get better with anything you try, it's a good idea to chat with a trusted grown-up about it.
