Help me destress

My story:

Got fingered, may have had some pre cum on bfs hand. (Not sure) Might have been exposed to air for a little prior. He did end up cumming to oral sex but he finished in a condom. No sex whats so ever. This was Feb.10, my period was due yesterday (feb19) and it came. Bright red and heavy. pregnancy test this morning negative. Safe to assure I’m not pregnant?
