Equate digital pregnancy test

So I have been ttc baby #2 for 6 months. Took a digital 5 days ago and got a “Not Pregnant”. Today is predicted AF day, no period but just cramps. I have been cramping (light cramps) for about 3 hours. So, I took a equate digital test just to get it over with, and it says “pregnant”. I expected a negative. I never had a late period.

I still think I’m not pregnant because of the cramps... idk

Has anyone had a false positive with equate digital ?
