Scared to get my hopes up.

I had an hsg test done 3 weeks ago on November 21st. I usually have a 29 day cycle. But glow says my period will start on the 31st cd (I know the app is not that accurate). But I’m really confused with this cycle. It’s now cycle day 30. I have no symptoms of my period coming. My boobs aren’t even sore like they usually are. I have been having random dull cramping. But that’s it. Has anyone had this and it turned into a bfp? I’m not testing until Thursday. But I’m scared I’m getting my hopes up.
