Is this my period or what could it be?

I had sex on December 17, 2023 (he used a condom, then cleaned himself and went at it without the condom) on December 19, 2023 i got my period which ended on the 23rd. Again I got my period two weeks after on January 3rd, 2024 and it lasted until the 7th. Can there be a chance I coulve got pregnant?
