Had unprotected sex last night ttc and took yeast infection treatment same day will the treatment prevent sperm from fertilizing the egg?

Within a very short time upon ejaculation of normal healthy mobile sperms into your vagina, hundreds of thousands sperms enter a receptive mid cycle cervical canal on their way to the uterus/tubes (and ?egg)
