Extreme Stomach Pain

Roxy

So I haven’t had a period since December. Which is not good. But my period tends to pull disappearing acts for a few months only to show up again at the worst times. But when it disappears I get this terrible pain that feels like period cramps and is only resolved by heat. It goes away if I take a hot shower or use a heating pad. I plan on going to the doctor but I’m scared of what might be wrong. But I desperately want the pain to stop.
