Bunpro Frequency Setting

Hello everyone I was studying through the vocab section and up with お腹 wanted to check its general frequency and realised it doesn’t exist also tried to check it with Yomitan it didn’t show anything either.

So my question is even though there are usages such as in the image is it worth to learn it, and if it is, is this like a general usage for stomach

Yes, it’s a very common word. Rank 2,023 means you’ll hear it constantly.
