Symptoms are gone?

I’m 13 DPO today, BFN yesterday and testing again tomorrow.

For a solid week (4 DPO to 11 DPO) I had lots of pregnancy symptoms. Sore breasts (which is very uncommon for me), nausea, vague cramping, etc. but for the last 2 days, my symptoms are mostly gone. I still have some intermittent cramping that is never severe, but my breasts feel normal and the nausea is gone.

Any one else have this happen? I have NOT been symptom spotting, I’m sure these symptoms were very real and now they’re very gone. Have you had symptoms like this, have them disappear and then still get a BFP? Am I just crazy??
