Yeast infection discharge? *TMI*

I’ve had some discomfort during sex and at the end of urinating lately. My s/o complained of having discomfort while peeing as well and got tested at the doctors because of it, they said they’d call back if the tests were positive and he never heard anything back (it’s been a month since then). He hasn’t had any issues since then but we had sex a couple days ago and he finished inside me, I smelled a bit fishy for a day after but it went away and now I’m having discharge like this. Could this be due to a yeast infection?
