feedback please!!!!

So I’m new to this and I know that the “heat of the moment” is no reason to have sex without protection ... but this was my first time having sex without condom. He pulled out. Should I be super worried? I should start my period within the next week and I’m scared that if I get paranoid over what could potentially be nothing at all, it will push my period back and I will get even more scared about the situation. HELP. Advice, anything , thank you!!!
