A common confusion is to mistake FICO (who makes the scoring algorithm) for myFICO (which makes a credit monitoring tool that our OP likely has purchased). It's best to think of them as if they were completely separate companies. They are not, but you'll be less surprised if you think of them that way.
The makers of a credit monitoring service (and there are many of these CMS's out there) often create "alerts" that are triggered by changes to your report. But the developers of a CMS don't know anything about how the actual scoring algorithm works. And the "alerts" they give you only apply to some of the changes on a report -- many such changes are not alertable, as the other commenters have explained.
You may find that all these alerts are confusing and are (for you) not worth paying $40/mo for. Many people decide that, though others like the myFICO product. Brutal Body Shots and I are people who pay almost nothing for our scores and reports, but we nontheless get our scores and reports frequently. There are lots of zero cost or ultralow cost approaches we can suggest if you are interested.
And of course, if you describe what is on your reports right now, any number of people here can explain what steps you need to take to improve your score.
