Slight cramping can be normal around the time that you miss your period.
FYI we do have a daily symptoms thread and there's probably a few others that are experiencing these symptoms. Or if you do a search in the search bar at the bottom of the page (on mobile at least, not sure about the full site) you can find more posts about cramps.
Re: Cramping
To answer the question, yes, they are normal as long as they aren't accompanied by bleeding and aren't severe and isolated to one side.

Good luck to you as well!
