get_the_content with <p>

I’m trying to get the post content, using get_the_content() to make a plugin that translates my blog posts from Spanish to English

The problem is when I use in loop $post = get_the_content()
It retrieves only text without <p> </p> between blocks of texts, so google translate returns a bunch of words without html formatted.

How I can get the post content ( formatted, purified or processed, I don’t know how to say ) with paragraphs?

Thanks in advance.
sorry my bad english.
