didn't have or didn't had the chance? Bear in mind or Bear in your mind?

I didn’t have the chance to see or didn’t had the chance to see? Bear in mind or Bear in your mind? Which one is correct???

I didn’t have the chance to see.

bear in mind

What’s wrong with didn’t had the chance or bear in your mind? Is it because native speaker didn’t say it that way?

“didn’t had” is wrong, as in the negative of past simple,with an auxiliary verb the main verb should be put in the first form. ( infinitive without “to”). You can say " I had no chance" but " I didn’t have the chance"

Thanks Bee, may I ask in which conversation I can use Bear in mind, is it polite?

Thanks, tamta. Now I understand.
