Could I get pregnant?

So me and my boyfriend had sex with a condom on the second last day of my period but I finished him by giving him a blow job. I swallowed most of the cum but i took my mouth away and some cum got on my hands but I’m almost sure I wiped it on the towel but then I touched my panties to put them on because it was dark. Could there be a chance that cum got on my panties and could get inside my vagina? I know I’m probably over reacting but I get freak out easily
