so question ?

hi so my question is my partner and i were fooling around (no penetrative or oral sex or sex of any kind really) and we felt what was likely pre ejaculate through my partners boxers as i was on top of him im not exactly sure if it went onto my underwear but i am currently on week 2 on my current ring cycle for birth control but my purse was stolen in the early morning of the 31st and was due to put my ring on the 31st in the afternoon so i had to wait until late on the 1st as i was away from home (so about 29 hours later) when i was able to travel back home to insert a new one we are just concerned because we know its a low chance but still a possibility of fertilization and we dont want that

thanks
