Late period

Charlene

My bf and I are trying to have a baby and I’m 7 days as of today .My period has never been late before, NEVER! . I took two pregnancy test and both came out negative. I feel mild cramps , and lower back hurts a little .

Could I still Be pregnant even though pregnancy test were negative ? My bf thinks maybe it’s soon for the results to be accurate . This over thinking it’s driving me crazy . Please HELP!!
