Help Me please

So this is an emergency. I had sex like 6 days before my period and then my period came early like not even 3 days after that. Then it was like crime scene level blood. And it ended early. Then i had the what could've been the stomach bug. Then today my bladder just decided without even letting me know i had to go to pee. Could i be pregnant? Should i be worried? Someone please help me🙏🙏🙏
