really dumb question

posting this anon bc it’s really dumb but i’m concerned and a little upset. we have been ttc over two years and for first time ever I finally got him to bd twice after my positive opk. so tonight I got on top and apparently he came and I didn’t realize so I stayed on top (sitting upright) another three min or so. do you think all the sperm came out of me ? 😩😩😩
