um.. what is this?!?😩😩😩

okay so i’m just standing up walking around and all the sudden i feel my body releasing something. like you know when you get your period and you feel ig come out? yeah. just like that! but i knew it couldn’t have been my period because i just got off of it . so im worried and go check and this is what i see . ( look at picture ) it’s like i peed on myself. but i didn’t . it’s so weird. i dont know what that can be but i know its not normal for me . it was more yellow thick stuff but i kinda touched it too see what it was . can someone help me ?? *side note* i had unprotected sex not too long ago but he didn’t cum in me. well that’s what he says . i dont know . and my boyfriend were having sex again when the condom slid off in my vagina...
