Cramping question!

So AF should come in 2 days (that's what glow says) but, I have had lots of cramping right after ovulation for like 5 days in a row. This hole month after ovulation I just never got the excitement thinking I could be pregnet. I still don't think I am pregnet.  (Just a feeling) I took a test yesterday just Bc glow said I should take one today and I wanted to see just in case and it was A BFN. Anyways back to my point I always get cramps right before AF and now I have nothing and I never have cramps after ovulation but I did this time. Anyone have this happen to them? It's Kinda got me worried... Thanks for the help all good luck!! ✨Baby dust to everyone ✨
