MacBook Pro keyboard issue
hello, my MacBook Pro keyboard randomly puts dots at the end of words when typing. In Mail.app, Word, Facebook and some others. Surprisingly none when I'm typing this message. Any ideas how to fix this?

You do not say what exact Mac /model /year /size /retina /touchbar is this
or
what exact macOS you are currently running?

You can try rebooting, you can Try resetting NVRAM/PRAM http://support.apple.com/kb/ht1379
If the issue continues you can trouble shoot further:
Try a SafeBoot https://support.apple.com/en-us/HT201262
Takes noticeable longer to get to the login screen, does a 5-15 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc.
This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.
