5-7 days before period BFN any hope?

Samantha

Haven’t been tracking my ovulation completely but I’m guessing I ovulated Around 20-22 due to my period is very regular. Wondering- took a test 5-7 days before my period and got a BFN. I have on n off cramping since 4 days ago and I had sore breasts now maybe once in awhile I do. Could I still be pregnant? Any hope? Initially thought for sure a week ago even woke up one morning super nausea but Now I don’t feel like I am. 😩
