Dry humping and pregnancy. Am i safe?

On oct 15th,me and my partner did some dryhumping with clothes on. I wore three layers of clothing leggings,shorts and undies. He only wore his shorts. His penis got out of his shorts so he ejaculated on my leggings near the waist elastic band and I cleaned it with tissues. For some minutes(5-7min) we were in each other's embrace. My leggings are not fully dried and there's a damp wetness near the ejaculated area on leggings.I had pcos and irregular cycles. For the last 2 months i had regular periods. LMP October 8th, 2022. In november also I had my period i.e; on November 6th. But my periods are somewhat scanty. I had brown bleeding for 5 days but it is more than spotting and less than a heavy flow. My question is, Will I get pregnant if he touched my leggings where he ejaculated and fingered me? Am i safe? He only rubbed on my clitoris and didn't enter the vaginal hole.
