Possibility??!

A week ago today my boyfriend and I got sexual. The furthest it went was me grinding on him naked. He tried to go in and it barely went it and it was too painful and lasted 3 seconds. He didn’t cum but my period is due tomorrow and I have no symptoms of even getting it. My period is irregular but eve has been doing a good job of keeping up. Should I be worried?

Edit: I have yet to get my period. I’m getting worried. Also no symptoms of a period. Not even my normal sore boobs
