Trying hard for a baby

Hey guys so I have a quick question that may sound dumb but I'm curious..🤔Soo after my bf and I have sex and he finishes inside me, I go to the shower bc I don't feel like sitting with "him" inside me the rest of the night😂 but my question is if im washing down there after is there a smaller chance I can get pregnant? We've been trying for months and I just..ugh I'm just worried about everything. Again, sorry I know this is probably a very stupid sounding question but I need peace of mind..😭
