Did you know what you can do after you have made a FB post and catch a spelling error or want to edit your post? I often see people make a comment after they realize they have made a spelling error without realizing what tools are available if you click on the 3 dots to the right of your post. It took me forever to realize the power of the dots. 
There is also a free tool with Grammarly that helps when writing and editing one's posts. https://www.grammarly.com/
To edit a post you've shared on Facebook:
Go to your post.
Click in the top right of the post.
Click Edit post.
Make your changes.
Click Save.
If photos are included in your post, keep in mind:
In most cases, you can delete photos without deleting the entire post. Hover over any photos you'd like to delete and click in the top right of the photo.
To add more photos, or other items to your post, click Add to your post.
You can't delete photos from your post if you shared your post from a third-party app (example: Spotify, a news site) or a photo album.
