should I worry

yesterday my period ended and my boyfriend and I also had unprotected sex. he pulled out before finishing but when he finished I.T came out really fast and like went everywhere. he was fucking me from the back and I was like leaning over and he was trying to let I.T like go on my ass cheek but some went in my back and idek. He said none went near my vagina but then he wiped towards my vagina with a towel so I’m scared that some of I.T went towards or in the direction my vagina. My period just ended and my ovulation isn’t predicted for another 2 weeks so I should be fine either way I think right?
