Am I pregant ??!

Okay well on June 29 I was sitting on this dudes part but we both had clothes I had a pad underwear and jeans he did too! He got a boner and cummed. On July 30 I got my period but it was short idk if it was that I was scared that I was pregnant that it made it like that. But I’ve been getting my period since then every month. Could I be pregant?! I recently went to the hospital I’ve been feeling bloated and they did Urine and blood test. Help me?!!
