Unless you ovulated late, then it's not highly likely. You only have that 24 hour window at the most, where the egg is viable and ready to be fertilised. If you had sex a few days before ovulation (which is the best time to be doing so if you're TTC) Then chances would be higher. But unless you track your ovulation you don't know for certain if you did ovulate on that day or not, so it might be possible. All you can do is wait and see if your next period shows.
