We were both aroused and getting moist but I had panties and Nike shorts on and he had shorts and boxers on. He didn't mean to but he ejaculated and we both ran to clean up because of fear that they might travel through clothing. I noticed my wetness and a little moisture from him on the edge of my shorts and a tiny bit below but very close to the crotch. I wiped off and changed but I'd like to know if it's possible I'm pregnant. I also have irregular periods so I don't know when my next one is and it was already over the regular time for a period before this scare. Is there a chance I'm pregnant and how soon can I take a test to find out?
