Odor after sex

Okay so please no rude comments: so if my SO and I have intercourse I always notice the next morning (cause we normally have it at night cause our schedules) that I have w odor. Not a fishy odor just an odor after we have sex the next morning or even sometimes afternoon. It's normally like when I start leaking what I think is his cum. It's only after he has cum in me and when it starts to leak out. Has anyone else had this? Is it a bad thing? We are trying to get pregnant also so I'm worried if it's leaking maybe when I am ovulating it's not reaching where it needs to.
