Misscarrage after math pains normal?

I had a misscarrage when I was 17. About 2 years ago and every now and then I still get pains in my ovaries that make me feel like I'm having the misscarrage over again that last a couple seconds. I talked to my doctor and he said it's normal because I was so young. But it still worries me. Should I go get checked again? Or am I over thinking this?
